ABSTRACT:
A charge coupled device (CCD) circuit suitable for low level input signals, e.g., from a photodiode, is disclosed. A low noise bias current source directly injects a current into a metal-oxide-semiconductor (MOS) device in order to increase the transconductance of the CCD, consequently extending the bandwidth of the CCD without increasing output noise levels.
