In this paper, a high-speed encoder intended for a 5GS/S 4-bit flash analog-to-digital converter (ADC) is presented. To meet the speed and power targets of the ADC, low-swing signaling is used in all the internal sub-blocks of the ADC including the encoder. To further enhance the speed performance of the encoder, 2-stage pipelining is utilized. In addition, the encoder is implemented in current mode logic (CML). The circuit is designed and simulated in a 0.18 mum CMOS technology. It consumes 4 mW from a 1.8 V supply while operating at 5 GHz
