A pipeline voltage-to-time converter for high resolution signal extraction off-chip

In this paper a pipelined voltage to time converter is presented. It is targeted at the extraction, in digital form, of sensitive analog signals from an integrated circuit. The tester is able to measure the period of this signal and derive the original voltage. The input signal is low frequency. This paper provides solutions to the main challenges in implementing this modulator and how it may be integrated with a digital tester.
