Abstract: This paper introduces a ring oscillator based novel DDFS technique for generation of fixed period synthesized output signal. Generally it is seen that DDFS designed using arithmetic circuits (Direct Analog) and loop based technique’s (PLL/VCO) provides synthesized signals with instantaneously varying time periods from a fixed period input clock signal. This type of synthesized signals create a major bottleneck when used in sensitive & precise application due to its time varying nature which in turn puts tight constraints on reference clock, power supply and system noise. In the presented work a RO based complete digital block ASIC architecture has been designed in which properly modulated input clock signal from RO is utilized to obtain a fixed period synthesized output signal. Presented synthesizer can be suitably incorporated for design of low power & area constrained VLSI architectures or programmable low scale integration processes with incorporated wide bandwidth range & low power consumption . Simulation result justify the proposed algorithm’s validity and its improvement in performance over arithmetic and loop based architecture’s
