专利汇可以提供Exponential transconductance multiplier and integrated video processor专利检索,专利查询,专利分析的服务。并且A linear transconductance multiplier of the type having a pair of transistors connected in common emitter configuration to a source of tail current, and having each base of the transistors connected through respective diodes to another current source, is modified so as to provide an output (voltage or current) which is a function of a fractional exponent of the input (voltage or current) by placing a diode in series between each emitter and the tail current source. The diodes may be shunted by a switch so as to provide selectivity between linear and exponential functions, or the diodes may be partially shunted so as to adjust the exponential function between unity (linear) and the minimum exponent obtainable. Providing additional diodes in series with the transistor emitters decreases the exponent further. An integrated video processor comprises an exponential transconductance multiplier having differential inputs with contrast control provided by adjustment of the tail current, gamma correction being achieved automatically by the nonlinear function of the multiplier; the multiplier output is fed to a brightness-controlled, final amplifier.,下面是Exponential transconductance multiplier and integrated video processor专利的具体信息内容。
