Abstract :
This paper deal with a square-wave relaxation oscillator with a high temperature-steadiness of the oscillation frequency. A conventional relaxation oscillator is first considered. Then, a modified version with a reduced temperature coefficient of its oscillation frequency is proposed. A temperature stability of the oscillation frequency below the 5% in the range [-40÷125]°C is discussed and evaluated by means of time domain simulations.
