October 1, 2009[Ideas For Design] Create A Mixed-Mode Precision Rectifier With Second-Generation Current Conveyors
RECTIFIERS PERFORM AN IMPORTANT signal-processing function in many analog circuits. But conventional half-wave, full-wave, or bridge rectifiers employing diodes can’t be used with low-amplitude signals. The circuit described below is a mixed-mode precision rectifier that can handle both low-amplitude voltage and current signals. Many previously described precision rectifiers use voltage op amps, but conventional voltage op amps suffer from a...
May 21, 2009[Ideas For Design] Current-Mode Multiplier/Divider Design Eschews Passive Components
This circuit design for a current-mode analog multiplier/ divider is based on current-controlled conveyors (CCCII) and a second-generation current conveyor (CCII). No passive components are used. Analog multipliers and dividers are important building blocks in signal processing and are widely used in modulation systems. Also, for the same two inputs, the multiplier changes to a squaring circuit, which provides the energy content of the signal. ...
April 9, 2009[Ideas For Design] Simulated Grounded Inductor Needs No External Capacitors
Inductors designed with active elements are very desirable to designers today because conventional spiral inductors are too big, too heavy, and too costly, and they require tuning. During the last few decades, various grounded inductors have been created using different high-performance active building blocks, such as operational amplifiers and operational transconductance amplifiers. But op amps suffer from a finite gain-bandwidth product (GBP) and GBP interdependence,...
