✦ Synopsis

Abstract

This letter proposes a divide‐by‐3 frequency divider employing the linear mixer topology; the divider was fabricated in the 0.35‐μm CMOS 2P4M CMOS technology. The divider consists of an nMOS cross‐coupled LC oscillator and two injection MOSFETs in series with the cross‐coupled nMOSFETs. At the drain bias voltage of 1.2 V, the divider free‐running frequency is tunable from 3.73 to 3.92 GHz, and at the incident power of 0 dBm, the operational locking range is about 0.69 GHz, from the incident frequency 10.99 to 11.68 GHz. The core power consumption is 6.9 mW. The die area is 0.83 × 0.94 mm^2^. © 2010 Wiley Periodicals, Inc.
