A 64dB gain 60GHz receiver with 7.1dB noise figure for 802.11ad applications in 90nm CMOS
A 60GHz receiver for 802.11ad application with superior performance in 90nm CMOS process, compared with prior arts in advanced processes, is proposed and realized. A 3-stage differential LNA achieves a gain of 19.8dB and a noise figure of 6dB in measurement, showing less than 0.3dB difference from simulation due to the elaborate consideration of parasitics. A baseband PGA with wideband and large gain tuning range is achieved from modified Cherry-Hooper amplifier with negative capacitive neutralization technique. The entire receiver achieves a double-side-band NF of 7.1dB and a maximal conversion gain of 64dB with 28dB tuning range, while consuming only 177mW of power. The measured output P1dB is -5.5dBm. All measured results are rigorously loyal to the simulation.
