Abstract
A continuous-time delta-sigma modulator, CTDSM () is described that comprises: an operational transconductance amplifier, OTA, () having an input port () configured to receive an analog input signal and an output port (); an input low pass filter network comprising at least one input resistor, R1, () at least one first shunt capacitor, C1, () and at least one feedback resistor, Rdac () connected to the input port of the OTA; an output filter network comprising a shunt second resistor, R2, () in parallel to a second shunt capacitor, C2, (), and coupled to the output port () of the OTA; a quantizer () connected to the output filter network and having at least one output connected to the input port of the OTA via the at least one feedback resistor, Rdac; and wherein the input and output port of the OTA connected by a third feedforward-feedback capacitor, C3, () arranged to provide a positive feedback around the OTA.
