A Log-Domain Wave Positive Impedance Inverter

Abstract

A new log-domain building block for log-domain filter design is proposed in this paper. This block realizes a positive impedance inverter (gyrator) by using the log-domain wave method. A simple procedure for log-domain filter development, using the proposed block, is outlined. This method results in circuits, which are simple in structure and very easy to design. An example of a second-order bandpass filter is given and its functionality is verified through simulations.

A Topology of Step-Down Resonant Switched-Capacitor-Based AC–DC Converter for High-Frequency AC Distribution

“…The technical concept and design of modular converters, also called building block, has been proposed. [1][2][3] Function-module application solutions support more e®ective development of electronic systems; each function comes with a high-performance module. For example, high-performance main control unit (MCU), driving controller, recti¯er bridge and modular SMPS became basic elements in the design of devices and the electronic power systems (EPS) used in many applicationsfrom commercial to aerospace, 4 which shorten the system developing time, reduce the number of parts and help their system engineers build and maintain higher performance and greater functionality into new products.…”
