A new realisation of an electronically tunable first-order voltage-mode all-pass filter enjoying the feature of low voltage and low power is proposed in this paper. The proposed realisation of filter employs only one active element namely differential voltage extra-x current controlled conveyor and ...
Replacing the all-pass network by a composite filter, comprising the all-pass network cascaded to an RC integrator, the system is seen to generate a continuous oscillation for a certain gain condition of the amplifier. Analysis of the two systems is made separately and the theoretical results ...

The proposed current-mode (CM) first-order all-pass filter employing a DX-MOCCII, a grounded capacitor, and a grounded resistor is shown in Figure2. Routine analysis of the circuit, using (1), yields the following transfer function: Proposed cascadable current-mode first-order all-pass filter...
Second-Order Butterworth Low Pass Filter The figure shows the circuit model of the 2nd order Butterworth low pass filter. In the circuit we have: Voltage ‘Vin’ as an input voltage signal which is analog in nature. Voltage ‘Vo’ is the output voltage of the operational amplifier. ...
This paper presents a canonical current-mode first-order allpass filter using two current controlled conveyors (CCCIIs) and a single grounded capacitor. The proposed circuit simultaneously realizes both inverting and non-inverting types of first-order allpass functions without needing component matching ...
The RC filter consists of two first-order all pass filters each containing an operational amplifier and connected to give either low pass or high pass characteristics. In the low pass circuit the first operational amplifier (1) has its RC circuit capacitor (C1) in series with its non-inverting...
It behaves exactly as a first-order low-pass filter in the sliding mode and is globally convergent. Its discrete-time implementation is based on the implicit (backward) Euler discretization, which does not result in chattering. The differentiator is validated through some numerical examples....

A novel first-order all-pass filter is proposed. Consisting of level shifters and two passive components, the circuit uses just six transistors to achieve desired phase shifts at near unity gain in a 3.3 V, 0.35 m CMOS process. Experimental results using 4007 ICs confirm the operation of ...
