Chapter 1, Problem 19E Step-by-step solution Step of 4 Draw the transconductance amplifier circuit. + + V₀ Figure 1 Step 2 of 4 The amplifier is fed from a voltage source having a resistance and the output is connected to a load resistance, as shown in Figure 2. i₀ + + + RL V₀ Figure 2 Step 3 of 4 Calculate the voltage across the resistance Rᵢ using voltage division rule. Rᵢ (1) Calculate the current, using current division rule. Calculate the output voltage. Substitute = (2) Step 4 of 4 Substitute for in equation (2). From the equation, it is known that, That is, Therefore, Thus, the overall voltage gain of the transconductance amplifier,
