Abstract

Abstract : A new two‐dimensional oscillator array‐based injection‐locked frequency divider is proposed. Instead of using the conventional analogue tuning technique or the one‐dimensional delay chain, a two‐dimensional array is implemented to digitally and precisely control the total delay in the oscillator core. This makes it possible to achieve a programmable delay, hence attaining potential programmable division ratios for the injection‐locked divider. Fabricated in a standard 0.18 μm CMOS technology, a prototype chip, namely a divide‐by‐4/5 prescaler using this technique, is able to work up to 6.2 GHz with 0.5 mW power consumption from a 1.8 V supply voltage.
