C- Amplifier: Consider figure 3. This circuit uses the JFET to amplify the input signal voltage First the dc operation must be set. Use equation 1 and your previous data to calculate the value of Vas required to give I-0.5 mA. Determine the source resistance Rs needed to set this bias. Set up the circuit of figure 3 with your calculated value of Rs. Measure Vo and Vs to determine if your operating conditions are correct. Apply an input voltage...
4. A sinusoidal signal was used as the input to the inverting amplifier below. The op amp is ideal except for its open-loop gain. It has an open loop de gain (Ao) of 100dB and a unity-gain bandwidth (f) of 100 MHz. a) Find the transfer function, H(o), including the non-ideal open loop gain, A. b) Find the 3-dB frequency for the op amp, and sketch the |Al vs. frequency graph. Label the open loop de gain, 3-dB frequency, and...
Problem 3: Design Problem On Figure P3a, you have a Common Source (CS) n-channel MOSFET amplifier. Notice the absence of a source resistor Rsig and load resistor R. If we know how the present amplifier (the one on Figure P3a) behaves without Rsig and RL, we can infer its behaviors if Rsig and R were to be added. design the amplifier circuit on Figure P3a, i.e., you have to find appropriate values for RGj You are to RG,, RD, and...
