AC Temperature Compensation of Integrated Amplifiers
Abstract
Effort is expended towards an analytical basis for temperature compensation of the AC performance of transistor small-signal amplifiers. Described is a simple, accurate design theory in which this compensation is analytically determined by imposing the requirement of equality for the values of the individual small-signal fourpole parameters of the amplifier at its operating temperature limits. For values of T between -30 degree C and +100 degree C in a typical noncompensated circuit, power gain, input impedance and output impedance vary by 99 percent, 71 percent, and 22 percent, respectively, while the comparable compensated circuit variation of each of these quantities is less than 9 percent. In an integrated circuit a single tapped resistance, properly selected, is the temperature sensitive element required for this compensation.
