Abstract
An operational amplifier may include a transimpedance input stage. The operational amplifier is capable of self-biasing its input voltage(s) including a first stage, an input source connected to the first stage, an output stage connected to the first stage via feedback resistors, and feedback current sources connected to the first stage, wherein the feedback current sources are set to generate feedback currents flowing from the output stage back to the input stage via the feedback resistors, so as to self-bias the input voltage(s) at the input stage. A method for allowing for an op-amp to self-bias its input voltage(s), including generating feedback currents flowing from the output stage back to the input stage via feedback resistors, so as to self-bias the input voltage(s) at the input stage.
