What is CS amplifier?

In electronics, a common-source amplifier is one of three basic single-stage field-effect transistor (FET) amplifier topologies, typically used as a voltage or transconductance amplifier. The easiest way to tell if a FET is a common source, common drain, or common gate is to examine where the signal enters and leaves.

How to Calculate Frequency at Zero Transmission of CS Amplifier?

Frequency at Zero Transmission of CS Amplifier calculator uses Frequency = Transconductance/(2*pi*Capacitance Gate to Drain) to calculate the Frequency, The Frequency at zero transmission of CS amplifier formula is defined as the transfer function of a linear two-port network that has zero transmission. Transmission zeroes at zero frequency and infinite frequency may be found in high-pass filters and low-pass filters respectively. A transfer function may have multiple zeroes at the same frequency. Frequency is denoted by f symbol.
