Abstract
A static frequency divider by using the back-gate coupling technique is presented. The proposed circuit has been fabricated in a 90 nm CMOS process. Driven by the differential signals, the measured operating frequency range of the conventional circuit is from 4 GHz to 48 GHz, while that of the proposed circuit is from 4GHz to 54GHz by choosing the same device size. The measurement result shows that the proposed static frequency divider improves the operating frequency range by 10% with only a little overhead. The maximum power consumption is 39.7 mW from a 1.5 V supply voltage.
