Analog circuit for calculating square and reciprocal of a current
An analog circuit for calculating square and reciprocal of a current is provided. It is an analog integrated circuit and can make the input and output signals become currents in the current field of the same type of analog integrated circuit. The output current can be the square or reciprocal of the input current. The square and reciprocal functions can be implemented by using three identical BJTs. Those three BJTs are independent and the bases and collectors of the BJTs are coupled to ground. Hence, the circuit can be implemented by the standard CMOS and can be applied to the other complicated system. In addition, the operational amplifier and the capacitor in the circuit are required to stabilize this circuit. This circuit has a simple structure.
