摘要

This paper describes a dual-channel 23 (20 to 27) Gbps chipset designed in a 40-nm CMOS process for 40 Gbps differential quadrature phase-shift keying (DQPSK) optical transmission. The transmitter has a 2-tap FIR filter and generates two channels of full-rate data. Data outputs exhibit 10 ps rise/fall times, 0.2 psrms RJ, 0.8 pspp DJ, and a ±0.5 UI skew adjustment relative to the full-rate and hal...
