WebSee Answer. Question: Design a voltage controlled current source (within the operating limits of the LM358 op- amp) where the output current is equal to 0.1V. (t) mA. (Vs (t) is the input voltage). Q1. Consider the voltage to current converter circuit in Fig. 1. a) Find the output impedance of this VCCs using Thevenin's theorem. Web3 jan. 2024 · Op-amp inverting amplifier = op-amp V-to-I converter + I-to-V converter. Note that the resistor R 2 serves here as the load L from Fig. 5). This circuit will amplify power, if the output power is greater than the input one. So, the output voltage has to be higher than the input one because the current is the same. WebQuestion: Project Howland Current Source & Deboo Integrator A.
