Abstract
This paper presents a time-interleaved pipelined-SAR converter targeting a multi-band mobile communication receiver. The input buffer is based on a super-source follower and linearized by selecting a specific bias current and drain bias resistor. Time interleaved sampling time mismatch is resolved by using a common sample and hold circuit, and gain mismatch is corrected by fine tuning respective subADC voltage reference. The prototype is implemented in 28 nm FD-SOI and achieves an SNR/SNDR/SFDR/FOM of 56.9/56.1/65/154 dB, consuming 89 mW including input buffer, voltage references, bias with bandgap and clock circuitry.
