Small Signal Input Voltage given Transconductance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Small Signal = Input Voltage*(1/(1+Transconductance*Resistance))
V_ss = V_in*(1/(1+G_m*R))
This formula uses 4 Variables

Variables Used

Small Signal - (Measured in Volt) - Small signal is an AC signal (more technically, a signal having zero average value) superimposed on a bias signal (or superimposed on a DC constant signal).
Input Voltage - (Measured in Volt) - Input voltage is the voltage supplied to the device.
Transconductance - (Measured in Siemens) - Transconductance is the ratio of the change in current at the output terminal to the change in the voltage at the input terminal of an active device.
Resistance - (Measured in Ohm) - Resistance is a measure of the opposition to current flow in an electrical circuit. Its S.I unit is ohm.

STEP 1: Convert Input(s) to Base Unit

Input Voltage: 2.5 Volt --> 2.5 Volt No Conversion Required
Transconductance: 1.72 Millisiemens --> 0.00172 Siemens (Check conversion here)
Resistance: 1.13 Kilohm --> 1130 Ohm (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_ss = V_in*(1/(1+G_m*R)) --> 2.5*(1/(1+0.00172*1130))

Evaluating ... ...

V_ss = 0.849300176654437

STEP 3: Convert Result to Output's Unit

0.849300176654437 Volt --> No Conversion Required

FINAL ANSWER

0.849300176654437 ≈ 0.8493 Volt <-- Small Signal
