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.

Abstract: Apparatuses, systems, and methods are disclosed for offset trimming for differential amplifiers. An apparatus includes a differential amplifier. A differential amplifier includes a non-inverting input, an inverting input, and an output coupled to the inverting input via a voltage divider. A first variable current source is coupled to a non-inverting input, so that increasing a current from the first variable current source increases a voltage at the non-inverting input. A second variable current source is coupled to an inverting input, and to an output via a voltage divider, so that increasing a current from the second variable current source decreases a voltage at the output.
