Publication number: 20230421164Abstract: In a pipelined Successive Approximation Register Analog to Digital Converter, SAR ADC, a Process, Temperature, and Voltage (PVT)-dependent bias voltage is generated and used to bias the inputs of comparators in at least the first SAR stage and residual amplifier (RA). This achieves a stable biasing and an operating point of the comparators and RA input stages that is independent of PVT variations, by tracking PVT variations in such a way that variations in MOS threshold voltage and drain-source voltage are counteracted. Additionally, a threshold common mode voltage is generated from the PVT-dependent voltage, which controls the amplification duration of the RAs such that the final RA output common mode voltage is substantially equal to the PVT-dependent voltage, which is used to bias the inputs of successive SAR stages. The threshold is set to account for logic delays in terminating the amplification based on the threshold comparison, to achieve the desired common mode amplifier output.Type: ApplicationFiled: December 3, 2020Publication date: December 28, 2023Inventors: Christer Jansson, Mattias Palm
