WebMay 22, 2024 · This amplifier uses zero bias, therefore ID = IDSS and gm = gm0. gm0 = − 2IDSS VGS ( off) gm0 = − 2 × 6mA − 0.75V gm0 = 16mS This amplifier is not swamped so we may use the simplified equation for voltage gain. Av = − gmrD Av = − 16mS(2.7kΩ 15kΩ) Av = − 36.6 Finally, for the input impedance we have Zin = 5MΩ Zin ( gate) ≈ 5MΩ WebThis changing ability makes it able to perform both as an “Amplifier” or a “Switch”. It can be used either as a switch or an amplifier at a single time. Therefore, BJT can operate in three different regions to perform the said operation. Active Region: In Active region, one of the junctions is in a forward bias while the other is in reverse bias.
