摘要：
A high energy-efficiency K-band on-off keying (OOK) transmitter in tsmc (TM) 90 nm CMOS technology is presented. The transmitter consists of a wideband voltage control oscillator (VCO), a frequency doubler and a switch-type power amplifier with a chip area of 0.6 x 0.92 mm(2). The VCO adopts a parasitic capacitance reduction technique to enhance the tuning range to 20.5%. The designed transmitter achieves an output power of 3 dBm with a 500 Mbit/s data rate from 19 to 23.1 GHz at 22.3 mW power consumption. The correspondent energy-efficiency is 44 pJ/bit.
