A 60GHz CMOS Differential Receiver Front-End Using On-Chip Transformer for 1.2 Volt Operation with Enhanced Gain and Linearity

Abstract

A compact 60GHz CMOS differential direct conversion receiver front-end based on eight-metal-layer interleaved on-chip transformers is realized for low voltage (1.2V) and high gain (24dB) operation with input 1dB compression point of -11dBm, noise figure of 10.5 dB and power consumption of 4.3mW/arm. Compared with prior arts in CMOS, this receiver achieves the highest gain without an output buffer, highest linearity, lowest noise, and lowest power consumption with smallest die area of 0.022mm2
