Line 1: ~~{{Orphan\|date=February 2009}}~~ [[Image:CDBA block.gif\|thumb\|270px\|Block diagram of the CDBA]] Line 12 ⟶ 11: #<math>Vw=Vz</math>. Here, the current through the z-terminal follows the difference ofbetween the currents through p-terminal and n-terminal. Input terminals p and n are internally grounded. The difference of the input currents ~~are~~is converted into the output [[voltage]] Vw, therefore CDBA element can be considered as a special type of current feedback amplifier with differential current input and grounded y input. The CDBA is ~~simplifying~~simplifies the implementation, is free from parasitic capacitances, able to operate in the frequency range of more than hundreds of MHz (even GHz!), and suitable for current mode operation while, it also provides a voltage output. Several voltage and current mode continuous-time filters, oscillators, analog multipliers, inductance simulators and a PID controller have been developed using this active element.
