DIFFERENTIAL AMPLIFIER CIRCUIT

摘要

PURPOSE:To prevent the amplification factor from being lowered by connecting a signal input line to a gate of the 2nd field effect transistor (TR) through a DC non-blocking delay circuit. CONSTITUTION:A voltage taking a level by a signal input voltage V0 is given to gates of field effect TRs Q1, Q2 except from the point of time of level conversion that the signal input voltage V0 given to the gate of the field effect TR Q1 changes from a high level to a low level or vice versa till the point of time taking the delay time of the DC non-blocking delay circuit 20. Since a voltage taking the same level is given to the drains of the field effect TRs Q1, Q2, no bias condition difference is given between the field effect TRs Q1 and Q2 except from the point of time of level conversion of the signal input voltage V0 till the point of time of delay time of the circuit 20.
