摘要
Relaxation oscillator circuitry is presented with low drift and native offset cancellation, including an amplifier amplifying a first current signal to provide a pulse amplifier output waveform, an integrator integrating a second current signal to provide a ramp output waveform, and a comparator comparing the integrator output waveform with a threshold set by the amplifier output waveform to generate an alternating oscillator output used to switch the polarities of the first and second current signals.
