摘要： A digital-to-analog conversion circuit operates by selectively discharging members of a plurality of capacitors. Charging of the capacitors occurs during a reset period while digital-to-analog conversion occurs as the capacitors are discharged. Those capacitors that are discharged are selected from the plurality of capacitors based on a digital input. The analog output includes the charge discharged from the capacitors. The capacitors are optionally divided into separate capacitor banks.

The capacitive divider circuit includes first and second inputs, across which, in use, is received a high voltage AC signal and also includes second and third capacitors. First and second plates of each of the first, second and third capacitors are defined by conductive layers of a printed circuit board and the dielectric of each of the first, second and third capacitors being defined by a non-conducting part of the printed circuit board. A compensator circuit has a configurable transfer function and includes an input connected across the first and second plates of the third capacitor and an output. The compensator circuit is operative to change a voltage received at its input in accordance with the transfer function and to provide the changed voltage at its output.

摘要： A system for driving a first signal onto a wireline includes a driver and feedback circuitry. The driver drives a deterministic signal onto the wireline with an unknown impedance load. The feedback circuitry measures a quality of the output signal from the wireline and modifies a signal strength of the first signal based on the quality of the output signal. The driver then drives the first signal onto the wireline with the modified signal strength.
