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.
