Abstract
An apparatus relating generally to voltage conversion includes an amplifier coupled to receive an input voltage and a reference voltage. First and second converters are coupled to the amplifier to receive a bias voltage. The first converter includes a first transconductor coupled to receive the bias voltage to adjust a first tail current, and a first differential input. A first inverter of the first converter has a first feedback device coupled input-to-output to provide a first transimpedance amplifier load. The first inverter is coupled to the first transconductor. The second converter includes a second transconductor coupled to receive the bias voltage to adjust a second tail current, and a second differential input. A second inverter of the second converter has a second feedback device coupled input-to-output to provide a second transimpedance amplifier load. The second inverter is coupled to the second transconductor.
