Title: Variable resistance circuit, operational amplification circuit, semiconductor integrated circuit, time constant switching circuit and waveform shaping circuit
Inventor: OTSUKA TAKESHI
IPC: H03G1/00
Filed: 2001-02-28
Abstract: PURPOSE: A variable resistance circuit is provided to reduce the area of a circuit, to set its resistance with high accuracy and to enhance frequency characteristic of an arithmetic amplifier circuit by reducing the parasitic capacitance. CONSTITUTION: In the variable resistance circuit, 8 resistors(T1-T8) whose resistance is Rx2i(i=0-7)(ohms) are connected in series, 8 switches(S1-S8), the resistance of parasitic resistors in an ON-state of which is rx2i(ohms) are respectively connected in parallel with the resistors(T1-T8), and the resistance of the variable resistance circuit is changed by turning on/off the switches(S1-S8). A resistor(T9) is connected between an inverting input terminal of an operational amplifier(1) and a terminal(N1) and the input terminal, which is not capable of inverting, receives a prescribed reference voltage. A variable resistance circuit(VT) constituting a negative feedback loop is connected between the inverting input terminal and the output terminal of the operational amplifier(1), in which the resistor(T1) and the switch(S1) are connected to the output terminal and the resistor(T8) and the switch(S8) are connected to the inverting input terminal. The resistance of the resistors(T1-T8) being components of the variable resistance circuit(VT) sequentially increases from a terminal(N3) and the resistance of the resistor(T8) connected to the inverting input terminal is highest. Since only one node ahead the final resistor(T8) exists and the parasitic capacitance is small, the frequency characteristic of the operational amplifier circuit can be enhanced.
