Abstract
An oscillator circuit selectively charges and discharges a capacitor with currents having variable magnitudes. A trimming circuit functions to measure a half period of the oscillator signal. The measured half period is compared to a reference period to generate an error signal. The variable magnitudes of one or the other or both of the current for sourcing or sinking at the capacitor are adjusted in response to the error signal.
