Abstract

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.
