The current-supplying circuit (120) includes a common-mode feedback circuit (CMFB) and an assist circuit (TA).

The invention can be used in the automotive field, for example in an assisted-braking circuit.

A write assist circuit may also be used to improve performance.

The assist circuit (TA) feeds a fixed amount of the second actuating current irrespective of the level of the reference potential VREF.

Methods and apparatus to control voltage output of a write assist circuit are disclosed.

Optionally the monitoring circuitry (100) which has the functionality for capturing system properties may be combined with other monitoring circuitry, which has the functionality required by a debug support circuit (300).

In addition, supporting circuitry can be incorporated onto the same device in a single manufacturing process.

The write assist circuit further includes a transistor (60) to receive an enable signal to couple the bit line to a low voltage rail (38).

The charge pump assist circuit may be implemented to toggle the output at a higher rate than the voltage level shifter.

The electrical signal output from the photodiode is routed through a bandpass filter, demodulated in a demodulator and amplified and/or processed in the hearing aid circuit.
