Abstract: A TD converter is provided for digitally converting a delay time value into a digital value. In the TD converter, an oscillator circuit part inputs time domain data. A first-state counter circuit part measures a number of waves of an output oscillation waveform from the oscillator circuit part when time domain data is in a first state, and a second-state counter circuit part measures a number of waves of the output oscillation waveform from the oscillator circuit part when the time domain data is in a second state. An output signal generator part generates an output signal based on output count values of the first-state counter circuit part and the second-state counter circuit part, and a frequency control circuit controls the oscillator circuit part to always oscillate and to control an oscillation frequency of the oscillator circuit part.

Abstract: 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.
