Abstract: Image sensor quality can be affected by power supply ripple caused by different loads on the power supply or through electromagnetic interference affecting the image sensor reference supplies. Improved reference voltage supplies are disclosed, minimising the effects of power supply ripple through Ahuja compensation and utilising parasitic capacitance.
