# Transconductance

The transconductance of a device is the ratio of the change in output voltage to the change in input current. It is a measure of the ability of the device to convert input current into output voltage.

##### What is transconductance and why is it important?

Transconductance is a measure of how well a transistor can amplify a signal. The higher the transconductance, the better the transistor can amplify a signal.

Transconductance is important because it determines how well a transistor can amplify a signal. The higher the transconductance, the better the transistor can amplify a signal.

What is transconductance of an amplifier? The transconductance of an amplifier is a measure of the ability of the amplifier to translate a change in input voltage into a corresponding change in output current. It is typically expressed in units of mhos (Siemens), and is a key parameter in determining the overall gain of the amplifier.

#### Why is transconductance called GM?

The transconductance of a device is the ratio of the change in output current to the change in input voltage. It is typically denoted by the symbol gm.

The term "transconductance" is derived from the fact that the output current is proportional to the input voltage. In other words, the device conducts a current proportional to the input voltage.

The term "transconductance" is also used to describe the gain of an amplifier. In this context, transconductance is the ratio of the change in output voltage to the change in input current.

### Why is it called transconductance?

The term "transconductance" is used to describe the relationship between the current flowing through a device and the voltage applied to it. In other words, it is a measure of how well a device can conduct current in response to a voltage.

The word "trans" in this context means "across" or "through," and the word "conductance" refers to the ability to conduct current. So, "transconductance" literally means "the ability to conduct current across a device." What is the unit of transconductance? The unit of transconductance is the siemens (S). Transconductance is a measure of the ability of a circuit to convert a small change in voltage into a large change in current.
