| Popis: |
This paper proposes a novel architecture for purely voltage controlled oscillator (VCO) based 1-1 MASH secondorder analog-to-digital converter (ADC). Each stage of the MASH uses an open loop inverter based ring VCO. The proposed ADC uses phase information from all inverters in the VCO in both the MASH stages to perform efficient multi-bit quantization. A novel VCO quantization error extraction circuit is proposed to easily extract quantization noise of the first VCO stage. A gain calibration for the second stage of the ADC has been analyzed. Behavioral simulations have been performed to validate the proposed architecture. |
