Voltage-to-time converter and method for operating the same

Abstract

A voltage-to-time converter is provided, which includes a first amplifier stage, a second amplifier stage, and an inverter. The first amplifier stage is configured to receive a first input voltage and a second input voltage and generate a first voltage signal with a first slew rate in response to a differential voltage between the first input voltage and the second input voltage. The second input voltage is higher than the first input voltage. The second amplifier stage is coupled to the first amplifier stage and is configured to convert the first voltage signal into a second voltage signal with a second slew rate using a hybrid complementary push-pull structure. The second slew rate is higher than the first slew rate. The inverter is coupled to the second stage and is configured to convert the second voltage signal to generate a time representation signal.
