Title: Differential amplifier
Inventor: HINOOKA KIYONOBU
IPC: H03F1/26
Filed: 1991-06-06
Abstract: PURPOSE:To reduce a noise level of an operational amplifier by selecting a mutual conductance of a differential transistor(TR) to be thrice or over of the mutual conductance of a load TR. CONSTITUTION:A differential input stage of a CMOS operational amplifier is formed by using N-channel MOS TRs M3, M4 as differential TRs and using P-channel MOS TRs M1, M2 of mirror connection as load TRs. Then the mutual conductance of the differential TRs M3, M4 is set to that thrice or over of the mutual conductance of the load TRs M1, M2. Thus, the effect of noise in the load TRs M31, M2 is neglected.
