A compact wide-locking range divide-by-4 static divider for mm-wave applications

Abstract

A wide-locking range divide-by-4 static frequency divider for the mm-wave wireless applications is proposed. The capacitive-bridged inductive shunt peaking technique is investigated for widening the locking range and a compact layout area. The divider is realized in 65nm LP CMOS with a small area of 100μm × 160μm occupied. Measurement results show the present divider achieves an operation range percentage of 35.2%, from 34GHz to 48.5GHz with a current consumption of 25mA at 1.2V supply voltage.
