Similar to this, even p-channel depletion-type MOSFETs can be used to perform switching action as shown by Figure 4. The working of this circuit is almost similar to the one explained above except for the fact that here the cut-off region is experienced only if V i = V G is made positive such that it exceeds the threshold voltage of the device. …5.1 DC (Bias) Circuit Dc circuits for the grounded-source amplifier are shown in Fig. 5.1 (PMOS). The circuit in (a) is based on a single power supply, and the gate bias is obtained with a resistor voltage-divider network. The circuit in (b) is for a laboratory project amplifier. Both and are negative, since the source is at ground. There is PMOS Transistor: A positive-MOS transistor forms an open circuit when it receives a non-negligible voltage and a closed circuit when it receives a voltage at around 0 volts. To understand how a pMOS and an nMOS operate, you need to know a couple key terms: Closed circuit: This means that the electricity is flowing from the gate to the source.
