Abstract: This paper shows a structure of current starved inverter-based CMOS thyristor oscillator which is utilized to drive the counters that go about as a segment in the elapsed time counter. The performance of this oscillator is improved using a temperature independent biasing circuit that utilizes low power. The design incorporates utilization of trim bits at different process corners to shift the frequency. As the oscillator works with a battery supply, the output variations across supply are compromised. On – chip oscillator is implemented in a silicon area of 0.003064 mm² using UMC180 CMOS technology. Output shows a low power low frequency performance compared to a regular on- chip oscillator.
