A 1GS/s 82dB Peak-SFDR 12b Single-Channel Pipe-SAR ADC with Harmonic-Injecting Cross-Coupled-Pair and Fast N-replica Bootstrap Switch Achieving 7.5fj/conv-step

High-speed medium-resolution ($\geq$ 10bits) ADCs enable direct RF sampling transceivers, which eliminate mixers and hence the troublesome mixing spurs. However, one major limitation of direct RF sampling is its limited SFDR/SNDR at RF frequencies mainly due to the challenge in designing a single-channel ADC with high speed and high linearity. This paper presents a 1GHz-ERBW 1GS/s 12b single-chann...
