A 4th-order 4-bit continuous-time delta-sigma modulator (CTDSM) employing single-amplifier biquad (SAB) based loop filter and an interpolating quantizer is presented. By adopting the SAB-based topology, the proposed loop filter achieves 4th-order noise shaping function with only two op-amps. Furthermore, the proposed twin-T SAB minimizes the latency of the excess loop delay (ELD) compensation path...
This paper presents a digital background linearization technique for VCO-based delta-sigma ADC. The nonlinearity of the VCO in the main ADC is mitigated with the aid of the reference OP-based delta-sigma ADC and the digital least-mean square (LMS) correction algorithm. The reference ADC provides sufficient linearity performance as the calibration reference to form an inverse transfer function of the...
A power-efficient continuous-time delta-sigma modulator (CTDSM) employing a single-amplifier biquad (SAB) based topology is proposed. The modulator incorporates a proposed twin-T SAB topology where the excess loop delay (ELD) is compensated by injecting a feedback signal into an internal node of the SAB while cooperating with an additional phase-compensation resistor. A low-power time-to-digital converter...
