Abstract
An enhanced amplifier circuit includes an amplifier having an input and an output and a current source. A diode is coupled between the current source and the input of the amplifier. The enhanced amplifier circuit may include a number of current sources with associated diodes and amplifiers. The diode prevents the amplifier from interacting with some undesired properties of the current source, such as capacitance and resistance, prevents current sources from interacting with one another, and allows for the use of intrinsic properties of the diode to modify the current source output signal, among other advantages.
