ABSTRACT
One of the key building blocks of time-mode systems for processing analog signals is voltage-to-time converters (VTCs) that map a voltage to a time variable with its value directly proportional to the amplitude of the voltage. Although VTCs can be realized using complex circuits to achieve good performance such as a large conversion range and a good linearity, operational amplifiers whose performance scales poorly with technology are often required [1-3]. As time-mode circuits are digital circuits, the linearity of a time-mode system that processes analog quantities is largely dominated by that of its VTC. VTCs whose performance scales well with technology are critical to time-based signal processing.
