Suppose an op-amp is to be used to amplify 250 mV to 500 mV with an error less than 1 mV. Estimate the minimum required op-amp open loop gain

Design a voltage regulator to supply at least 50 µA of current at 500 mV with a VDD as low as 600 mV. Assume that a 500 mV voltage reference is available and that the load capacitance is, minimum, 1,000 p F. How does the design respond to a load current pulse from 0 to 50 µA? Use SPICE to verify your design.
