Abstract: The present disclosure provides a voltage-to-time converter and method for reducing parasitic capacitance and power supply influences. The voltage-to-time converter includes: a main sampling network, a compensation sampling network, a discharge network and an over-threshold detection unit. The influence of a traditional VTC parasitic capacitance on a VTC output swing amplitude is reduced by using the compensation sampling network. A sampling common-mode level of the compensation sampling network is compensated, such that the influence of the low-frequency disturbance of a power supply voltage on a threshold of a traditional VTC threshold detection circuit is reduced. The output swing amplitude of the voltage-to-time converter of the present disclosure can reduce the influence of a parasitic capacitance. A voltage common-mode level of a VTC input end is related to a power supply voltage, which reduces a conversion error caused by the influence of the power supply voltage on a threshold.

Abstract: A highly linear time amplifier with power supply rejection. In a reset stage, the threshold value of an over-threshold detector is used for resetting an output node of an amplifier, to eliminate the impact of power supply voltage changes on the threshold value of the threshold detector. A node capacitor unit is charged under the control of an input clock signal. After completion of charging, the node capacitor unit is discharged under the control of a synchronous clock signal. The time amplification gain only depends on the proportion of the charge and discharge current, and the charging and discharging time are completely linear in principle, which eliminates the nonlinearity of the traditional time amplifier, and reduces the negative impact of threshold change on system performance.
