Hey there.. need helps here..
The question is..
Derive an expression relating the output voltage, Vo to the input current, Iin.
The Attempt at a Solution
i try to derive it.. but..
got problem with RL
V1 = -IinRf
Vo =- R2/R1(-IinRf) how to include Rl in my derivation?
An ideal op amp, short for operational amplifier, is a type of electronic circuit component that is designed to amplify and process signals. It has two input terminals, a non-inverting terminal (+) and an inverting terminal (-), and one output terminal. In an ideal op amp, the input impedance is infinite, the output impedance is zero, and it has infinite gain and bandwidth.
A current to voltage converter is a circuit that converts an input current signal into an output voltage signal. It typically consists of a resistor and an op amp, with the input current flowing through the resistor and creating a voltage drop that is amplified by the op amp. This type of converter is commonly used in electronic applications such as sensor signal conditioning and current sensing.
In an inverting op amp configuration, the input signal is applied to the inverting terminal (-) of the op amp, while the non-inverting terminal (+) is connected to ground or a reference voltage. The output voltage is then the amplified and inverted version of the input voltage, with the amount of amplification determined by the ratio of the feedback resistor to the input resistor.
Using an ideal op amp in a current to voltage converter offers several advantages. Firstly, it provides a high input impedance, which minimizes the loading effect on the input signal. Secondly, it has a low output impedance, allowing it to easily drive loads without causing significant voltage drops. Finally, an ideal op amp has a very high gain, allowing for precise and accurate signal amplification.
An ideal op amp current to voltage converter is commonly used in electronic circuits for various applications. Some examples include current sensing in power supplies, signal conditioning for sensors, and audio amplification. It can also be used in instrumentation, such as oscilloscopes and data acquisition systems, to accurately measure and amplify small signals.
