Low-power programmable divider for multi-standard frequency synthesizers using reset and modulus signal generator

This paper proposes a low-power programmable divider for multi-standard frequency synthesizers using a reset and modulus control signal (RMS) generator. The use of RMS generator enables the adaptation of only one counter. This results in less power consumption and effective area. Our design also includes modified D flip-flop design. Proposed divider was designed and fabricated in a standard 0.18-μm CMOS technology Its divide ratio covers from 13 to 1278 at 3GHz. The average power is 3.58mW with 1.5V power supply and effective area is 0.0408mm
