Types of operational amplifiers
1.Classification according to the manufacturing process used Operational amplifiers can be divided into two types according to the manufacturing process used: CMOS and bipolar operational amplifiers. Since CMOS operational amplifiers are voltage-controlled devices, they operate with a low DC input bias current (I I), so their power consumption is low. However, due to the low withstand […]
What is an op-amp?
An operational amplifier (op-amp) is an integrated circuit (IC) that amplifies the difference in voltage between two inputs. It is so named because it was developed for perform arithmetic operations. Amplifiers, buffers, comparators, filters, etc. can be implemented with simple external circuits. An op-amp has five terminals: positive power supply, negative power supply (GND), noninverting […]
