  1. Describe the conditions under which an op-amp circuit willoscillate. Provide a technique to avoid undesirableoscillation.

  1. Explain why the gain-bandwidth product (GBW) is limited for anyamplifier, and why GBW is constant for a fully compensated voltagefeedback op-amp. If a fully compensated op-amp has GBW = 4 MHz, andits closed-loop amplifier circuit has gain (closed-loop gain) =100, what is the loop gain at 100 Hz?
