Design of Multi-bit Multi-phase Vco-based Adc
A design of multi-bit multi-phase VCO based ADC is presented in this paper. Time-domain quantization is done to extract the benefit from continuous scale down of technology Three stage current starved ring VCO is implemented using single ended delay cell configuration. A different method is used to increase the linearity of VCO and to increase the resolution of ADC in feed forward architecture,...

متن کاملImplementation of a Multi bit VCO based Quantizer using Frequency to Digital Converter
Voltage Controlled Oscillator (VCO) based ADC is unlike other ADCs. Input analog signal is converted into timing information via VCO then quantized in time. This paper demonstrates the multi bit VCO based quantizer using Frequency to Digital converter (FDC). Simulation result achieve in terms of SNR, SNDR and power dissipation. VCO based quantizer design using Cadence Virtuoso in GPDK 90nm tech...
متن کاملAn all-digital PWM-based ΔΣ ADC with an inherently matched multi-bit quantizer
An all-digital PWM-based delta-sigma (ΔΣ) ADC is proposed. This system takes advantages of the duration of a pulse, rather than voltage or current, as the analog operand used in its closed-loop operation. Unlike VCO-based ADCs, this ADC as a linear input sampling stage with adequate uncalibrated performance. Furthermore, the architecture allows inherently matched multi-bit quantizer/DAC blocks ...
متن کاملVco-Based continuous-Time Sigma Delta ADC Based on a Dual-VCO-quantizer-Loop Structure
This paper explores a continuous time (CT) sigma delta ( ) analog-to-digital converter (ADC) based on a dual-voltage-controlled oscillator (VCO)-quantizer-loop structure. A thirdorder ̄lter is adopted to reduce quantization noise and VCO nonlinearity. Even-order harmonics of VCO are signi ̄cantly reduced by the proposed dual-VCO-quantizer-loop structure. The prototype with 10MHz bandwidth and 400...
