Transistor differential amplifier
Abstract
Abstract IN A TRANSISTOR DIFFERENTIAL AMPLIFIER PAIR, A BIAS VOLTAGE RANGE IS ESTABLISHED FOR AN ASSOCIATED CURRENT SOURCE. WITH THE SELECTED BIAS VOLTAGE, THE CURRENT SOURCE COMPENSATES FOR TEMPERATURE VARIATIONS TO MAINTAIN GAIN OF THE DIFFERENTIAL AMPLIFIER PAIR SUBSTANTIALLY INDEPENDENT OF NORMAL TEMPERATURE VARIATIONS. A PRIMARY RELATION IS ESTABLISHED TO DEFINE THAT BIAS VOLTAGE WHICH CAUSES THE GAIN OF ANY TRANSISTOR DIFFERENTIAL AMPLIFIER PAIR HAVING KNOWN CHARACTERISTICS TO BE INSENSITIVE TO TEMPERATURE CHANGE. MORE COMPLEX AND SERIES-COUPLED DIFFERENTIAL AMPLIFIER CURCUITS MAY ALSO BE RENDERED TEMPERATURE STABLE, WITH RESPECT TO GAIN, WITHOUT THE USE OF TEMPERATURE COMPENSATING COMPONENTS.
