14.19 DX-CCII-Based Grounded Inductance Simulators

Figure 14.22 shows three single DX-CCII-based grounded inductance simulators
proposed by Metin [ 5 ]. The presented structures employ three resistors and one
capacitor and do not require any passive component matching condition. Assuming
ideal DX-CCII, the input impedance of these circuits can be obtained as:
