ADC (analog-to-digital converter): A circuit that converts an analog value, usually
voltage, to a digital value.
CDS (correlated double sampling): A method of compensating for noise in a CCD
system by subtracting two samples. The first sample is taken immediately after
reset, when the CCD output voltage is at the reset level, and the second sample is
taken when the CCD charge output is present.
Closed-loop gain: The gain of a circuit with feedback components added. For an
opamp circuit, this means that the feedback loop to one of the inputs is closed with
resistors or other components. Closed-loop gain may be an integer number, or it
may be an ...
