Abstract
A Bi-Directional and Adjustable Current Source (“BACS”) for providing an amplifier input with a voltage signal that is linear, where an output of the BACS and the amplifier input are shunted with a capacitor, is described. The BACS may include a first switch in signal communication with a high voltage reference and a first current source in signal communication with the first switch. The BACS may also include a second switch in signal communication with a low voltage reference and a second current source in signal communication with the second switch. The BACS may further include a directional current element in signal communication with both the first current source, the second current source, the output of the BACS, the amplifier input, and the capacitor, where the directional current element is configured to prevent current flow from the output BACS to the first current source.
