Abstract
An apparatus comprises: an OTA (operational trans-conductance amplifier) with a positive input terminal coupled to a reference voltage, a negative input terminal coupled to a feedback node, and an output terminal shunt to a ground node via a shunt capacitor; a resistor coupling the output terminal of the OTA to the feedback node; and a load circuit coupled to the feedback node via a switch controlled by a logical signal, wherein: an impedance of the shunt capacitor is substantially smaller than an input impedance of the load circuit. In an embodiment, the load circuit is a switch capacitor circuit. A corresponding method using an OTA is also provided.
