Question

What is the Thevenin equivalent open-circuit voltage of the small-signal circuit, as seen from the output port? Write an algebraic expression for this vout in terms of the parameters K and VT, the bias voltage VIN, and the incremental input voltage vin.

Answer 1

-vin

Answer 2

if correct please click best response

Answer 3

-vin. If you recall from the lecture sequence there's a phase inversion, which explains the minus sign.
