### Non-Inverting Amplifier Design and Analysis #### Problem 1 **a) Design a Non-Inverting Amplifier:** - **Objective:** Design a non-inverting amplifier with a gain of 100 using ideal op-amps and practical values of resistors. - **Task:** Draw a schematic of the circuit showing input, output, and all resistor values. **b) Effect of Input Voltage Range:** - **Scenario:** The amplifier is not ideal and has an input offset voltage of ±5mV and input bias currents of 100nA. - **Analysis:** If the input is 5mV, what output voltage do we expect? Show your calculations and consider how the range of the output voltage is affected since input is no longer ideal. **c) Calculate Output Voltage Using Superposition:** - Assume an op-amp with parameters: V\(os\) = 5mV and V\(_B\) = 100nA. **d) Common Mode Rejection Ratio (CMRR):** - **Questions:** - What is common mode rejection ratio (CMRR) and why is it important? - If your circuit has 80dB of CMRR and there is a ±100V sine wave noise signal, what will the common mode signal be present in the output? #### Problem 2 **Find Output Voltage:** - **Task:** Find the output voltage \(v_o\) in each of the 3 circuits below and explain how you found it. - Assume all op-amps are ideal. #### Circuit Diagrams Explained: - *Circuit 1:* - Inputs: \( V_1 \), \( V_2 \) - Resistances: 10kΩ, 100kΩ - OP-AMP with feedback and input resistor configuration. - *Circuit 2:* - Inputs: \( V_1 \), \( V_2 \) - Resistances: 10kΩ, 10kΩ, 20kΩ - OP-AMP with inverting non-inverting terminals and additional resistors in feedback. - *Circuit 3:* - Inputs: \( V_1 \), \( V_2 \) - Resistances: 30kΩ, 20kΩ, 10kΩ - Cascade configuration with OP-AMPs and multiple resistor network. #### Problem 3
