Discussion Overview
The discussion revolves around the operation of a PMOS transistor in source follower mode, specifically addressing the conditions under which it functions with a gate-source voltage (Vgs) of -5V. Participants explore the implications of this configuration and seek clarification on the behavior of the device.
Discussion Character
- Technical explanation, Debate/contested
Main Points Raised
- Hemant suggests that a PMOS requires a negative Vgs (th) to operate and questions the output behavior when both the gate and source are at -5V.
- Some participants request a circuit diagram and clarification on whether a PMOS or JFET is being used.
- A later reply indicates that the output behavior may be due to the gate and source being shorted together, noting that they are both at -5V with respect to ground, but not with respect to the source.
Areas of Agreement / Disagreement
The discussion remains unresolved, with participants exploring different aspects of the PMOS operation without reaching a consensus on the explanation for the observed behavior.
Contextual Notes
There are limitations regarding the clarity of the circuit configuration and the specific definitions of voltage references being used, which may affect the understanding of the PMOS operation.
