Operational floating current conveyor: characteristics, modelling and experimental results

Current-mode rectifier configuration based on OFCC

“…The Operational Floating Current Conveyor (OFCC) [2,3] circuit symbol is shown in Fig.l. The low impedance input port is designated as X whereas high impedance input port is named Y.…”

“…The development and application of current-mode processing [I] has given a tremendous boost in the State-of-the-Art analog integrated circuit design, The benefits of the current mode processing stems from the fact that the circuits based on it possess wider bandwidth, greater linearity and larger dynamic range, The operational floating current conveyor (OFCC) [2,3] is a versatile analog building block which combines the features of current conveyor and the current feedback opamp. It has both low and high impedance ports which can be used respectively for current and voltage inputs.…”

Single-Input Four-Output Current Mode Filter Using Operational Floating Current Conveyor

“…OFCC. The circuit symbol of operational floating current conveyor (OFCC) [23,24] is shown in Figure 1. It has a low impedance current input port and a high impedance voltage input port .…”

“…The structures-use excessive number of elements [6,7,13,15] some of the references cited in [17], do not present low input impedance [1,8,[13][14][15][16]19] which is necessary for a current mode filter, employ multiple inputs to provide output responses [15,16], put matching constraint [7,10,15,16] to obtain all five responses of universal filter, has less than three simultaneous output responses [4,8,15,16,21], employ different type of active blocks [12,19,20]. The operational floating current conveyor (OFCC) [23,24], which was introduced as operational floating conveyor (OFC) [25], combines the features of current conveyor and the current feedback op-amp along with additional current outputs that add flexibility in the circuit design. Literature survey on OFCC based circuits [26][27][28][29][30][31][32] shows that voltage mode filter [26][27][28], variable gain amplifier [29], wheatsone bridge [30], and instrumentation amplifier [31] and read out circuit [32]…”

Novel Cmos Realizations of the Operational Floating Conveyor and Applications

“…It worth noting that there are other blocks perform the same applications mentioned above such as the operational floating current conveyor (OFCC). 9 It has the same transmission properties as the OFC but with an additional current output terminal. This additional terminal output current is a negative replica of the output current at terminal Z.…”
