Abstract :
The evaluation of response time of a constant temperature thermoresistive sensor based feedback circuit, excited by a pulsewidth modulated (PWM) waveform is done by a way of simulation studies in PSPICE environment and compared with that of a circuit excited by an analog voltage (continuous time domain). For a thermoresistive sensor with an intrinsic time constant much larger than the period of the PWM waveform, the degradation in the response time of the PWM circuit is negligible.
