Dynamic supply column amplifier

Image sensors run wide parallel operations to process data. To reduce power consumption, it is desirable to use dynamic power down of modules, i.e. circuits are turned on only for short time for each read-out cycle.

Project tasks

Implement dynamic amplifier (the power supply is stored on capacitors, and the amplifier is turning itself off after the amplification).

Investigate how to handle single ended input.Study how to make (a single ended) topology and implement it in silicon.
