What is Current Conveyors (CCs)?

What is Current Conveyors (CCs)? Current conveyors (CCs) were first introduced by Smith and Sedra and have been used in a variety of electronic applications. The CC is a three-port device described by the hybrid equations in which symbols for the port variable represent total instantaneous quantities. a = 1 represents the first generation conveyor, …

OTA as Programmable Resistor, Grounded Resistor and Floating Resistor

OTA as Programmable Resistor, Grounded Resistor and Floating Resistor: OTA as a Programmable Resistor: We may employ Ic OTA as a programmable resistor whose resistance is controlled by controlling current Ic. We can define resistance, using Eq. (41.16) Two OTAs can be employed to behave as programmable resistor, as shown in Fig. 41.6. Now to …
