Low power band gap circuit

Image sensors (as most circuits) need a stable band gap reference for reference voltages and bias currents.

High performance bandgap voltage generator with ~mW of active power, and ~nW average power.
Normal band gap with sampled output.
Low leakage sampling switch, very long duty cycle.
Challenging because image sensors operate in a wide temperature range.

Assignment: Design and develop a band gap circuit with dynamic power off, short start-up time and low leakage sampling switches on output.
