发明名称 Operational amplifier circuit with improved gain of feedback loop
摘要 An operational amplifier circuit comprises an input amplification circuit, a driving circuit coupled with the input amplification circuit, and an averaging circuit for providing a feedback loop, and increases the magnitude of an input differential voltage signal so as to produce an output differential voltage signal, wherein an average voltage of output voltage levels of the output differential voltage signal is supplied to the input amplification circuit for increasing the gain of the averaging circuit.
