Using known op amp configurations, design and draw an op amp circuit to convert Farenheit to Celcius. C=5/9(F-32)

Solutions

Expert Solution

We will use Three Inverting Op-Amps with constant input signal of 9.7 Volts and a Fahrenheit input voltage signal VF. The circuit is as shown below.

(Note we are not using any 100 volts for 100 degree input for Fahrenheit Input voltage (High Voltages) nor we are getting 32 Volts at output. We are making it more in practical way)

i.e we can use Divide by 10 Multiplier to get VF  and x10 for displaying the value of temperature in Celsius

Describe the conditions under which an op-amp circuit will oscillate. Provide a technique to avoid undesirable oscillation. Explain why the gain-bandwidth product (GBW) is limited for any amplifier, and why GBW is constant for a fully compensated voltage feedback op-amp. If a fully compensated op-amp has GBW = 4 MHz, and its closed-loop amplifier circuit has gain (closed-loop gain) = 100, what is the loop gain at 100 Hz?
