A 4-bits active inductor-based lattice 24.5–50 ps all-pass filter

Single Active Element based Current-Mode All-Pass Filter

In this paper, a current-mode all-pass filter employing single multi-output dual-X second-generation current conveyor, a grounded resistor and a grounded capacitor is proposed. The circuit is as good as ideal for current-mode cascading by possessing low input and high output impedances. The use of grounded passive components makes the circuit, ideal for IC implementation. The effect of non-idea...

A BJT technology-based current-mode tunable all-pass filter

In this paper, a new bipolar technology-based configuration for providing inverting first-order currentmode (CM) all-pass filter response is proposed. One of the main advantages of the introduced active C topology is to have the property of electronic tunability of its pole frequency without requiring passive component matching condition. To show the performance of suggested filter, simulations...

6 GHz RF CMOS Active Inductor Band Pass Filter Design and Process Variation Detection

Ablindadaptiveequalizerbasedona Lattice/all-pass Connguration

Networks for the blind channel equalization can be designed as a combination of a prewhitening lter (adjusted by means of 2nd-order statistics) and an inverse all-pass system (adjusted by 4th-order statistics). In this paper an appropriate FIR approximation of inverse all-pass systems is presented. On the other hand the inverse all-pass modelling can be avoided if the minimum phase prewhitening...

Log-domain All-pass Filter-based Multiphase Sinusoidal Oscillators

Log-domain current-mode multiphase sinusoidal oscillators based on all-pass filters are presented in this paper. The first-order differential equation is used for obtaining inverting and non-inverting all-pass filters. The proposed oscillators are realized by all-pass filters whose natural frequency and stage gain can be electronically tuned by adjusting the bias currents. Each all pass filter ...
