Abstract
A gyrator includes a gyrator core and at least one common mode feedback circuit. The gyrator core includes four inverters mutually connected in a loop configuration between a pair of input ends and a pair of output ends. The common mode feedback circuit is provided between the pair of input ends and/or the pair of output ends and includes a forward-reverse connection inverter set and a backward-reverse connection inverter set. The forward-reverse connection inverter set has a first inverter, a second inverter connected in reverse series with the first inverter, and a first feedback resistor connected in parallel with the second inverter. The backward-reverse connection inverter set has a third inverter, a fourth inverter connected in reverse series with the third inverter, and a second feedback resistor connected in parallel with the fourth inverter.
