Need help with this problem down below.
Compare the closed-loop voltage gain, k = Vo/Vs, for the loaded and unloaded dependent source model of the Voltage Follower with the ideal model of the Voltage to examine the impact of the load, RL on k. - Using any circuit analysis method, derive expressions for the closed-loop gain, k = Vo/Vs, for the ideal opamp Voltage Follower ,both the unloaded ,loaded Voltage Follower using the dependent source model. simplify both of the closed-loop gain expressions for the dependent source models by applying the ideal opamp parameters: A --> infinity , R_i -->infinity and R_0 --> infinity.
