Resumen

Descripción

This document presents a 0.18 um CMOS process highly-linear Voltage-to-Time Converter (VTC) design that can operate at a low voltage of 1.8 V across PVT corners and with the power consumption of less than 13 uW and linearity error less than 1%. The VTC was designed to work at a minimum of 1.68 V and accepts a maximum clock frequency of 900 MHz; to reduce non-linear behavior a symmetric load and current starved inverter configuration was proposed. This circuit was designed using TSMC 0.18 um CMOS process technology.
