Abstract: An oscillator circuit includes a voltage controlled oscillator (VCO) configured to generate a clock signal having a clock period that is adjustable based on a control signal. The oscillator circuit includes a time to voltage converter configured to receive the clock signal and generate a compensation voltage potential that is proportional to the clock period and a zero temperature coefficient (ZTC) current. The oscillator circuit includes an amplifier configured to generate the control signal responsive to the compensation voltage potential and a temperature independent reference voltage potential. A method includes applying a control signal to a VCO, generating a clock signal having a clock period responsive to the control signal, generating a compensation voltage potential, and adjusting the clock period using the compensation voltage potential. A memory device includes the oscillator circuit.
