The Analog to Digital Converter (ADC) is similar to the ones used in DMMs by Rhode & Schwarz (UDS 5) and Solartron (7150). It’s a Voltage-To-Time converter like other integrating conversion methods, e.g. Dual Slope. This Voltage-To-Time converter circuit, comprising an integrator, a comparator, reference switching, converts the voltage output from the buffer amplifier into… Read more nanoDMM – ADC
