Voltage to Frequency Converter for DAC Test.
Proceedings of the SPIE, 5837.
In this paper a modified relaxation oscillator is proposed as the core of an analog to digital modulator for on chip signal
extraction for test. The architecture uses digital current source generation and digital switching in place of active
circuitry. The resulting design allows for high input sensitivity, robustness to component variation while occupying little
silicon area. This paper provides solutions on the main challenges in implementing this modulator and how it may be
integrated with a digital based tester.
