Negative emittance converter suitable for band passing - has one operational amplifier connected to circuit input and another to output

摘要

One operational amplifier's output is connected through an immitance, and its inverting input directly to the converter's first terminal. Its non-inverting input is connected through a resistor to its output and to the terminal at a reference potential. Another operational amplifier (OP2) is between the first amplifier's (OP1) inveting input and the input terminal (1). Its non-inverting input is connected to the terminal (1), and its inverting input to that of the first amplifier (OP1) and through a resistor (GA) to the converer's second terminal (2). Its output is connected through a resistor (GB) to its inverting input.
