op am

Describe the operation and the characteristic of the general-purpose 741 op-amp provided in the attached file. i) Derive and calculate overall gain. ii) Determine the unity-gain bandwidth iii) Compare between BJT (741) op-amp and BiCMOS (CA3140) op-amp.

Define appropriate resistor values in a battery-charger circuit

The attached file shows the circuit in question along with information about the components (zener diode, op-amp, and BJT transistor). Problem Statement: The simple circuit shown below is a battery-charge circuit. It operates from a DC power supply having Vcc=22V. The fully charged NiCd battery pack exhibits Vb=12.08V. Operation starts when switch S1 is opened. After the battery is fully charged, switch S1 is closed. Define the appropriate values of R1, R2, and R3. IMPORTANT NOTE: Disregard the verification process mentioned in the attachment (I can do this myself with PSPICE). I only need to be shown the method for achieving the resistor values.

[11.13] Power Electronics - A single-phase bridge rectifier

[11.13] A single-phase bridge rectifier has a purely resistive load R=10 Ohms, the peak supply voltage Vm=170 V, and the supply frequency f=60 Hz. Determine the average output voltage of the rectifier if the source inductance is negligible. ============================================= Answers: a) Vd=120.13 V b) Vd=113.32 V c) Vd=150.42 V d) Vd=80.41 V ================================================== =========================================== OTA: please take this problem only if you can show step by step problem solving. Thank you.

In schematics, ground and chassis may be assumed to be common, unless stated specifically otherwise. Unless otherwise specified, assume that the Op-Amp supply voltages are (see attachment for details)
