US Patent 11626885 Gain programmability techniques for delta-sigma analog-to-digital converter
Article
An excess loop delay compensation (ELDC) technique for use with a successive approximation register (SAR) based quantizer in a continuous time delta-sigma ADC is described. The techniques can efficiently program and calibrate the ELD gain in ELD compensation SAR quantizers. An ELDC circuit can include a charge pump having a digitally programmable capacitance to adjust a gain, such as the gain of the ELDC digital-to-analog converter (DAC) or the gain of the SAR DAC.
