Proposed current mode universal filter achieves multiple response types in signal processing, suggesting enhanced design efficiency.
In this research a minimum component current mode (CM) single input multi output (SIMO) universal filter is proposed. The filter employs one voltage differencing differential voltage current conveyor (VD-DVCC), two grounded capacitors and a single grounded resistor. The filter can realize low pass (LP), high pass (HP), bandpass (BP), band reject (BR) and all pass (AP) responses simultaneously. The working of the filter is validated by designing it in 0.18µm technology in cadence design software at a supply voltage of ±0.9V.
