Abstract :
A divide-by-16/17 dual-modulus prescaler (DMP) and two programmable & plus swallow dividers for application in a digital video broadcasting-terrestrial (DVB-T) receiver are designed in a 0.18mum 3.3V mixed-signal CMOS process. The master/slave D-flip-flop (DFF) in the DMP is made up of an improved D-latch to increase the speed and the driving capability. A novel D-latch architecture integrated with ´OR´ logic is proposed to decrease the complexity of the circuit. Post simulation results of the chip layout indicate that the proposed DMP works well at the frequency band of 1~2 GHz. The maximum operating speed is 2.4 GHz. The programmable & plus swallow dividers are directly synthesized by EDA tools and finally fabricated with 0.18 mum standard library.
