Design of a PRBS generator and a serializer using active inductor employed CML latch

Abstract

This paper presents an inductor less D-latch for high-speed integrated circuits. The proposed D-latch uses negative feedback, which makes the high-frequency input impedance appear inductive. This effect increases the bandwidth by about 23%. The proposed latch operation is verified using two highspeed integrated circuit applications, i.e., A pseudo-random binary sequence (PRBS) generator and a serializer. The PRBS generator and the serializer show an improvement of 15.8% and 23%, respectively, using the proposed latch. Results are confirmed using post-layout simulation in standard 90 nm CMOS technology with 1 V supply.
