Gamma Correction Amplifier

Mar 23rd 1992
This circuit shows a schematic of a typical circuit which can correct for positive or negative gamma. This is an upgrade of a classic circuit which uses diodes as the nonlinear elements. The temperature variation of the diode junction voltages is compensated to the fi rst order by the balanced arrangement. LT1227s and LT1229s ...
