Title: Circuit device for low distortion switching of signal
Inventor: HANSU KURIITO
IPC: H03K17/66
Filed: 1989-02-08
Abstract: PURPOSE: To make it possible to switch a signal at a low cost and low distortion by negatively feeding back an operational amplifier, setting up reference potential to the reference potential of the operational amplifier and applying the end point of a section to be switched by the output terminal and reference potential of the amplifier. CONSTITUTION: The operational amplifier mainly consists of push-pull stages T1, T2, differential amplifier stages T3, T4, a current mirror Q, and current mirror circuits Q1, Q2. The negative feedback of the operational amplifier is executed from the output terminal A of the amplifier to the base terminal of a 2nd transistor (TR) T4 to be the differential amplifier stage through a diode D4 having the polarity of a conductive direction. A signal to be switched is led to the output terminal A of the amplifier connected to the reference potential through a 2nd resistor R1. Since the influence of the amplifier to a signal format is slightly held by action as a short-circuit switch, circuit- technological cost can be reduced.

Title: Composite controlling amplifier
Inventor: TAKAGI SHIYUN
IPC: H03F3/72
Filed: 1982-02-26
Abstract: PURPOSE:To hold a terminal voltage of a load constantly, by controlling an amplifier to be controlled with a specific controlling amplifier. CONSTITUTION:When an operational amplifier 4 is controlled with a controlling amplifier 2, a saturation preventing current IS1 flows to a controlling amplifier 1' in this state. A prescribed relation exists among the IS1, an input voltage V1 of the amplifier 1' and an output voltage V0. Thus, when a switch SW2 is  opened and the control of an operational amplifier 4 with the amplifier 2 is blocked, the control of the controlling amplifier 1' is realized quickly. No spike voltage due to the controlling amplifier switching is generated. Since the operational amplifier 4 is controlled with the amplifier 1' exclusively, the output voltage V0 is unchanged even if voltages VM, V2, and V3 are changed.
