Low Power Digital ADC Architecture Using Reversible Logic Gatesin 65nm Technology

In the deep submicron CMOS technology, the planning of analog and complicated mixed could be a huge challenge. Therefore it's fascinating to shift converter from analog domain to the digital domain. The benefits of implementing a completely digital ADC style rather than ancient analog ADC style are that it's easy to design and implement. It offers low power consumption, smaller space and a completely optimized gate-level circuit that reduces the planning prices. The functioning of all-digital ADC relies on the time domain signal process approach, which brings time resolution obtained by the employment of CMOS technology. Digital ADC style is enforced by employing combination of the digital Voltage-Controlled generator and a Time-to-Digital device. The VCO converts the amplitude-domain analog signal to a phase-domain time-based signal. The time-based signal from the VCO output is then processed by the TDC quantizer so as to come up with the digital code sequences. Power is reducing by applying reversible logic concept to the digital ADC architecture. This paper presents the implementation of a VCO-based digital ADC in TSMC 65nm CMOS technology victimization digital tools like ModelSim simulator and Cadence RTL Compiler. A multi-phase VCO and multibit quantization design has been chosen for this 8-bit ADC. Keywords- Low Power, Digital ADC, Verilog HDL Coding, VCO Based ADC, Reversible Logic Gates
