Abstract :
This paper proposes a novel dynamic logic which not only has a lower output parasitic capacitance but also has a switchable characteristic to achieve the speed improvement in the application of programmable divider. The speed of some logic circuits is discussed in this paper. A 16-GHz divide-by-two frequency divider based on the proposed dynamic logic has been demonstrated in TSMC 0.13-mum CMOS process, too. After a successful simulation, the implemented frequency divider has an operating range from 10.5 to 16.5 GHz and a maximum input sensitivity of 5 mV in amplitude at 13.5 GHz under a supply voltage of 1.3 V and a core power consumption of 4.7 mW.
