This article proposes a dual-resonance CMOS LC-tank injection-locked frequency doubler (ILFD) fabricated in the 0.18 μm CMOS process and describes the circuit design, operation principle, and measurement results of the ILFD. The ILFD circuit is composed of a dual-resonance first-harmonic injection-locked oscillator with dual-injection ports, a wide-band frequency doubler, and a transformer balun. At the supply voltage of 0.7 V, the dc power consumption is 5.39 mW. At the incident power of 0 dBm, the ILFD has high/low operation range from the incident frequency 3.9/1.7 to 6.1/2 GHz to provide a dual-band signal source with the frequency 7.8/3.4-12.2/4 GHz. © 2011 Wiley Periodicals, Inc.
