Summary: This paper presents the design of new fully differential CMOS class A and class AB current-mode transmitters for multi-Gbps serial links. A high multiplexing speed is achieved by multiplexing at low-impedance nodes and inductive shunt peaking with active inductors. The fully complementary operation of the multiplexers and the fully differential configuration of the transmitters minimizes the effect of common-mode disturbances and that of EMI from channels to neighboring devices. Large output current swing is obtained by making use of differential current amplifiers and the differential rail-to-rail configuration. The constant current drawn from the supply voltage minimizes the noise injected into the substrate. The transmitters have been implemented in TSMC's 1.8 V 0.18 µm CMOS technology and analyzed using Spectre from Cadence Design Systems with BSIM3V device models. Simulation results confirm that the proposed transmitters are capable of transmitting data at 10 Gbps. | ||||||||||
