Abstract

Method and system for analog-to-digital conversion. According to an embodiment, the present invention provides an integrated circuit. The integrated circuit includes a different operational amplifier, which includes a first output, a second output, a first input, and a second input. The operational amplifier is associated with an amplification factor. The integrated circuit also includes a first voltage input. The first voltage input can be characterized by a first voltage. Additionally, the integrated circuit includes a second voltage input. The second voltage input can be characterized by a second voltage. Furthermore, the integrated circuit includes a first voltage source configured to provide a first reference voltage. In addition, the integrated circuit includes a second voltage source configured to provide a second reference voltage. Furthermore, the integrated circuit includes a first capacitor being electrically coupled to the first input and disengageably coupled to the first voltage input.
