发明名称 Inverting amplifier having a low noise biasing network
摘要 An operational amplifier with reduced bias circuit noise. The present invention reduces the noise contribution of the non-inverting input bias circuit. This noise reduction is accomplished by reducing the bandwidth of the bias circuit by bypassing high frequencies to signal ground. This reduces the noise voltage developed across the bias circuit and thereby reduces the noise at the output of the amplifier.
