Abstract :
This paper discusses bandwidth enhancement technique for high speed amplifier. Inductive peaking is a common practice for bandwidth enhancement, however the area occupied by on-chip inductors is a heavy disadvantage. We utilize mutually coupled inductors for effective inductive peaking. A Laser-Diode (LD) driver for optical communication system is designed in a 0.18μm CMOS. Measurement results show that the mutually coupled inductor can achieve 16Gbps operation and 26% area reduction compared to conventional shunt peaking.
