Pipelined ADC with a VCO-based stage |
摘要 |
A method for converting an analog signal to a digital signal is provided. Initially, a digital representation of a portion of an analog signal is generated. Residue of the analog signal is then sampled at a sampling instant so as to generate a residue sample. A signal having a frequency that is proportional to the voltage of the residue sample is generated, and the signal is measured to generate coarse and fine measurements of the frequency. A digital representation of the residue sample from the coarse and fine measurements is then generated.
