摘要： There is provided a gain control Gilbert amplifier circuit which can be more easily controlled for variation in the gain characteristics of each predriver integrated circuit for primary color image signals R, G, and B, and the variation caused by light emitting efficiency than the prior art. The gain control Gilbert amplifier circuit also operates in a wider frequency range than the conventional circuits, and has a large S/N ratio. One embodiment of the amplifier circuit comprises a grounded-base transistor amplifier circuit having rectifier elements, reference voltage sources, diodes connected to a differentially paired transistors. The rectifier elements are controlled so that a ratio of currents output from constant-current sources can be selected to enable the frequency characteristic of the amplifier circuit to expand by a frequency range.

摘要： A gain control circuit includes first and second clamping circuits each of which has a DC shift circuit and a comparator comprising the output of the DC shift circuit with a reference voltage and providing a feedback signal to the respective shift circuit. A peak detector is responsive to the output of the second clamping circuit and is connected with a comparator which outputs a gain control signal to a variable gain device or amplifier located between the clamp circuits and also to the comparators associated with the DC shift circuits for varying the follow-up speeds of the clamping circuits.
