Two new configurations for realizing ideal floating frequency-dependent negative resistor elements (FDNR) are introduced. The proposed circuits are symmetrical and are realizable by four CCII or ICCII or a combination of both. Each configuration is r

Based on the nodal admittance matrix (NAM) representation of the voltage mirror (VM)–norator pair and considering the case of an inverting second generation current conveyor (ICCII−), it is found that the second generation current conveyor (CCII

Two new types of floating current conveyors are introduced. Each type has four ports: Y, X and two Z ports. The first type is the Floating Second Generation Current Conveyor (FCCII) and includes both CCII+ and CCII- as special cases. The second type

This paper investigates the sensitivity of continuous-time (CT) delta-sigma analog-to-digital converters (ADCs), candidate architectures for multi-standard and software-defined radio receivers, to feedback pulse-width jitter (PWJ) in presence of bloc
