Abstract
This paper presents the design of an energy efficient Flash analogue-to-digital converter (ADC) with Threshold Inverter Quantiser (TIQ) comparator employing advanced body biasing to compensate for the effects of parameter variability. The proposed calibration scheme is verified against process, voltage, and temperature (PVT) corners as well as random parameter variability (mismatch). Two proof-of-concept ADCs of 4- and 6-bit precision are designed and verified in simulations in 28 nm Fully Depleted Silicon on Insulator (FDSOI) technology. The 6-bit converter achieves sampling rate of 3 GS/s, energy efficiency per conversion step below 20 fJ, and precision of 5.2...
