A transistorized operational amplifier has been developed which has a current gain of 2 × 106. The summing accuracies obtained are of the order of 0·1 per cent. To reduce the drift, the temperature of the amplifier is controlled and resulting amplifier can be used for various purposes as computing and measuring amplifier.
