ELECTRONIC CIRCUIT FOR TIMER APPLICATIONS HAVING MINIMAL POWER CONSUMPTION AND METHODS FOR CALIBRATING AND OPERATING THE SAME
The invention relates to a method for calibrating and to a method for operating an externally programmable electronic circuit, and to an externally programmable electronic circuit equipped to execute said methods. The externally programmable electronic circuit comprises a first oscillator (RCO) and at least one second oscillator (NFO), wherein the second frequency (1/T) of the second oscillator (NFO) is lower than the frequency (1/To) of the first oscillator (RCO). After a programmable time (tP) has expired, the circuit brings about the execution of a predetermined action by outputting a corresponding output signal, wherein the programming is done by modulation of a carrier frequency (fT). For calibration, the current period duration (TO) of the first oscillator (RCO) and a ratio corresponding to the ratio between the period duration (TO) of the first oscillator (RCO) and the period duration (T) of the second oscillator (NFO) are determined based on the known carrier frequency (fT). During the operation of the circuit, the time (tP) is programmed after or during calibration by way of modulation of the carrier frequency, wherein, after completion of the calibration and a start signal, the progression of the transmitted time (tP) is such that a corresponding fourth periodicity (M-1) of the second oscillator (NFO) and a corresponding third periodicity (q) of the at most intermittently parallel operating first oscillator (RCO) are counted.
