    Abstract: One feature pertains to a circuit comprising a semiconductor leakage source device and a semiconductor leakage cancellation device that are both coupled to a signal line. The leakage source device generates a leakage current on the signal line, and the leakage cancellation device generates a leakage cancellation current on the signal line. The leakage cancellation device is sized and shaped in relation to the leakage source device such that the leakage cancellation current effectively cancels the leakage current on the signal line. Moreover, the leakage cancellation current cancels the leakage current on the signal line despite variations in at least one of process, temperature, and/or signal line voltages. In one example, the signal line is a virtual ground node of a capacitive feedback amplifier and the leakage source device is a switch between the virtual ground node and a first terminal of a feedback capacitor of the amplifier.

    Abstract: A trigger circuit includes a first capacitor and a second capacitor connected in series, a control device and an output of the trigger circuit. The first capacitor is connected to a first voltage rail and to a common node. The second capacitor is connected to a second voltage rail and to the common node. The control device has a first terminal that is coupled to the common node and a control terminal to receive a control signal. The control signal may be decoupled from transients on the first voltage rail and the second voltage rail. The output of the trigger circuit is coupled to the common node.

    Abstract: An apparatus for supplying power to a load. The apparatus including a plurality of sources to provide charge, and a controller adapted to control a transfer of charge from the sources to the load at distinct times. The controller may control the transfer of charge based on variation of an ambient condition or a manufacturing process. The controller may control the transfer of charge to generate a defined voltage across the load. The apparatus may include a regulator adapted to regulate a voltage across the load. The regulator may regulate the voltage across the load in a defined timing relationship with the transfer of charge from the sources to the load.

    Abstract: Certain aspects of the present disclosure generally relate to a sampling network of a switched-capacitor integrator and a clocking scheme associated therewith, which may be used in an analog-to-digital converter (ADC), for example. The integrator generally includes five sets of switches which allow for a decreased switching frequency (e.g., halved) at an input stage of the integrator compared to conventional double sampling networks. As a result, the input impedance of the integrator may be increased (e.g., doubled), resulting in lower power consumption and reduced strain on driving circuitry.
