Abstract
Systems and methods can detect a relationship between portions of an analog input signal using a single sensing point, and can provide information about the detected relationship in a digital signal. A system can include an input transconductance stage, a gate circuit driven by a first control signal, a phase-select multiplexer circuit driven by a second control signal, and multiple analog-to-digital converter (ADC) channels. The ADC channels can include respective integrator circuits that receive information from the phase-select multiplexer circuit, and the ADC channels can include comparator circuits coupled to respective outputs of the integrator circuits. The outputs of the comparator circuits can be used as control signals for respective feedback multiplexers, or respective feedback current DACs, that selectively couple reference currents to the respective integrator circuit inputs. The feedback current DACs can be configured to continuously provide information to the respective integrator circuits.
