Abstract

An integrated circuit includes a fin having a height and a width under a gate of a selected fin-type field effect transistor (FinFET) that is less than the height and width along a remainder of the fin including under gates and for source/drain regions of other FinFETs. The IC includes a first FinFET having a first gate over a fin having a first height and a first width under the first gate, and a second FinFET in the fin adjacent to the first FinFET. The second FinFET has a second gate over the fin, and the fin has, under the second gate only, a second height less than the first height and a second width less than the first width. The resulting reduced channel height and width for the second FinFET increases gate control and reduces gate leakage, which is beneficial for ultra-low current leakage (ULL) devices.

Abstract

A semiconductor device includes a transistor including a gate and a dielectric layer over the gate. A cavity is in the dielectric layer above the gate and a portion of the cavity over the gate has a negative sloped sidewall in the dielectric layer. The negative sloped sidewall provides a portion of the cavity having a trapezoidal cross-section having a first width at a lower end adjacent the gate and a second width smaller than the first width at an upper end. The negative sloped sidewall thus places a wider portion of the cavity closer to the gate, which decreases gate-contact capacitance.

Abstract

A disclosed charge pump includes first and second stages and, optionally, additional stage(s). The first stage receives a voltage input (Vin) at a first voltage (V1), CLK1 (GND, V1), and CLK1B (V1, GND), and outputs a first stage voltage output (Vout1) at a second voltage (V2) double V1. A second stage receives Vout1, CLK2 (V1, V2), and CLK2B (V2, V1, and outputs a second stage voltage output (Vout2) at a third voltage (V3) essentially triple V1, and so on. A clock driver supplies CLK1-CLK1B to the first stage and to a clock generator. The clock generator includes: a voltage level shifter, which receives CLK1 and CLK1B and outputs multiple level-shifted voltage output pulses; and a driving circuit, which receives specific ones of the output voltage pulses and outputs CLK2 and CLK2B to the second stage and, if needed, additional voltage level-shifted clock signal-inverted clock signal pairs to any additional stages.

Abstract

To reduce sub-harmonic oscillations in a Switched-Mode Power Supply (SMPS). a ramp generator circuit of the SMPS produces a ramp signal having an amplitude corresponding to a sensed current through an energy storage device, such as an inductor, of the SMPS. The ramp signal is used to control a duty cycle of the SMPS. The ramp generator circuit may include a reference current circuit, a ramp capacitor, and a discharge circuit to periodically discharge the ramp capacitor. The ramp capacitor may be charged using a charging current produced by combining a feedback current corresponding to the sensed current with a reference current produced by the reference current circuit and may be periodically discharged at a fixed frequency, or may be charged using the reference current and discharged at a time determined according to the feedback current.

Abstract

Disclosed structures include a single-stage and a multi-stage voltage level shifter. Each structure includes multiple transistors, which are optionally all symmetric low-voltage transistors, and the structures are configured to avoid operation outside the safe operating area (SOA) of such transistors. The single-stage voltage level shifter and the first stage of the multi-stage voltage level shifter can be essentially identical. In operation, input voltage pulses (including an input voltage pulse transitioning between a first positive voltage (V1) equal to the voltage rating of the transistors and ground) can be received at source nodes of N-type transistors and, in response, output voltage pulses (including an intermediate output voltage pulse transitioning between V1 and a second positive voltage (V2) that is higher than (e.g., double) V1 and an output voltage pulse that transitions between ground and V2) can be output.

Abstract

A disclosed circuit structure includes a voltage level shifter connected to a variable voltage generator for receiving a low supply voltage and to a programmable voltage generator for receiving a high supply voltage that is higher than the low supply voltage. The high supply voltage is programmable to one of multiple different voltage levels. The variable voltage generator tracks the voltage level of the high supply voltage and outputs the low supply voltage based thereon. The high supply voltage is tracked either directly or using the trim bit signal employed by the programmable voltage generator to program the high supply voltage. The low supply voltage is high when the high supply voltage is high to ensure operation within the safe operating area and is low when the high supply voltage drops below some threshold level to ensure operability and, optionally, improve operating speed.

Abstract

A structure includes a level shifter, first and second variable voltage generators, and a programmable voltage generator. The level shifter includes low and high supply voltage nodes and two parallel branches, including multiple transistors, connected between the nodes. The programmable voltage generator generates and applies a high supply voltage (VH) to the high supply voltage node. VH is programmable to one of multiple possible VH levels. Based on the voltage level of VH, the first variable voltage generator generates and applies a low supply voltage (VL) to the low supply voltage node and the second variable voltage generator generates and applies a gate bias voltage (VGB) to gates of some transistors. By tracking VH and adjusting VL and VGB based on thereon, the voltage level shifter operates within the SOA at high VHs, remains operable at low VHs, and maintains operating speed at mid-level VHs.

Abstract

Systems and methods for designing photonic integrated circuits (PICs) include a simulation program with virtual optical probing functions and, optionally, bidirectional optical signal propagation simulation. For probing, a processor receives an output expression specifying a virtual optical probing function (e.g., for power in dBm, etc.) and a net within a PIC design. If different simulation types are enabled, the expression specifies simulation type. If bidirectionality is enabled, the expression specifies the forward or reverse direction. In response, the processor accesses the PIC design and results of simulation(s) thereof and calculates and outputs an optical signal parameter value for the specified net. For bidirectionality, component descriptions of photonic device cells define, at each input/output terminal, pins associated with each of multiple optical signal components in both directions and, when such cells are incorporated into a PIC design, analytical functions employ the pins to model the optical signal components in both directions.
