Title: Operational amplifier using complementary misfet
Inventor: YOTSUYANAGI MICHIO
IPC: H03F3/30
Filed: 1984-07-10
Abstract: PURPOSE:To obtain an operational amplifier circuit with low power consumption and large through-rate and a broad frequency band without decreasing its DC gain by using a complementary MISFET. CONSTITUTION:A signal inputted to an MOSFETM1 of MOSFET differential pairs is inverted by the M1, amplified by a common gate MOSFETM25 and inverted again by an MOSFETM29 via a current mirror circuit. A signal inputted to the differential pair in the differential input stage is inputted to a source of a common gate MOSFETM27, where the signal is amplified and outputted to a gain stage M30 after being converted into single form from the differential form. Since the MOSFETM30 is connected to a drain of a gate M28, a gate-source voltage of the M30 is increased, allowing to flow a lot of current. Thus, a load capacitor CL and a phase compensating capacitor CC are discharged and the through-rate is improved.
