This paper presents a new three inputs and one output current-mode universal filter employing one modified current differencing transconductance amplifier (MCDTA) and two grounded capacitors. The filter can realize low-pass, bandpass, high-pass, band-stop and all-pass responses by appropriately connecting the input terminals. For realize filtering functions, without component-matching conditions and...
This paper presents a new electronically tunable sinusoidal oscillator. The proposed oscillator is consisted of two second-generation current conveyors with variable current gain, two grounded capacitors, one grounded resistor and one floating resistor. Unlike previously oscillators, the condition and the frequency of oscillation of this oscillator can be controlled electronically and independently...
A design methodology and equations are described for lumped-element filter prototypes having low-pass, high-pass, bandpass, or bandstop characteristics with theoretically perfect input- and output-match at all frequencies. Such filters are a useful building block in a wide variety of systems in which the highly reactive out-of-band termination presented by a conventional filter is undesirable. The...
