A V-band wide locking-range injection-locked CMOS VCO for wireless network-on-chip receiver

This work presents a V-band wide locking-range injection-locked VCO (ILVCO) for a wireless network-on-chip (WiNoC) receiver. The design is aimed to achieve wide locking-range at low injection power so as to be used as a carrier recovery circuit in a low power receiver. Wide locking-range is achieved by means of enhanced transconductance injection in a complementary VCO. The ILVCO achieves a locking-range of 1.3 GHz at -10 dBm input power. The ILVCO, implemented in 65 nm CMOS process, occupies an active area of 0.024 mm² and consumes only 5.7 mW. The ILVCO has a 460 mV_p-p output swing and thus requires no buffer to drive a mixer.
