A 1V Low Voltage 4GHz Phase-Switching Dual-Modulus Prescaler in 0.18μm CMOS

Article Preview

Abstract:

A 1V low-voltage phase switching dual-modulus prescaler in standard 0.18μm TSMC RF CMOS technology is presented. Forward phase switching technique is used to prevent glitches. Low threshold voltage transistors are applied to overcome low voltage supply. Circuit techniques are used to improve driving ability and ensure reliability. The post simulation results show the prescaler operates correctly from 0.8GHz to 4GHz with power dissipation of 2.059mW at a maximum input frequency of 4GHz from 1V power supply.
