Its gain will be negative. For eg. if we provide sine wave input, its amplified output will be 180° out of phase with input. When the input is voltage is increasing, output voltage will decrease and vice versa. Recommended Reading : […]

As the name indicates it is virtual, not real ground. For some purposes we can consider it as equivalent to ground. In opamps the term virtual ground means that the voltage at that particular node is almost equal to ground voltage (0V). It is not physically connected to ground. This […]

Opamp is the abbreviation of Operational Amplifier. An operational amplifier is a direct coupled high gain amplifier usually consisting of one or more differential amplifiers followed by a level transistor and an output stage. The output stage is generally push-pull or complementary symmetry push-pull amplifier. Opamps are building blocks of analog […]

It is the building block of analog integrated circuits and operational amplifiers (op-amp). One of the important feature of differential amplifier is that it tends to reject or nullify the part of input signals which is common to both inputs. […]
