Top Questions on Op-Amps
- Express \(v_{\text{out}}\) in terms of \(v_{\text{in}}\) for the given circuit, assuming the op-amp is ideal.
- Considering the op-amp to be ideal, the \(v_{\text{out}}\) is expressed as:
- Calculate the output voltage of an op-amp for input voltages of \(V_{i1}=150\mu V\) and \(V_{i2}=140\mu V\). The amplifier has a differential gain of \(A_d=4000\) and the value of CMRR is \(100\):
- For an op-amp having a slew rate of \(4 \text{ V}/\mu s\), what is the maximum closed-loop voltage gain that can be used when input signal varies by \(0.1V\) in \(10\mu s\)?
