A new versatile building block: current differencing buffered amplifier suitable for analog signal-processing filters
A new multi-terminal active component with two inputs and two outputs, namely current differencing buffered amplifier (CDBA) is proposed. It is derived from current feedback amplifier (CFA) which is commercially available as AD844. It has been shown by realising high-order voltage transfer function that it is beneficial to use this element as a building block to realize analog signal-processing filters.
