Abstract

This article proposes a divide‐by‐3 frequency divider (FD) with quadrature outputs fabricated in the 0.18‐μm CMOS technology. The current reuse and the back‐gate coupling techniques are adopted. Measured results show that the free‐running frequency is from 1.173 to 1.25 GHz. The proposed FD can cover the input frequency from 3.51 to 3.8 GHz at the incident power of −3 dBm. © 2009 Wiley Periodicals, Inc.
