An On-Chip Automatic Tuning Circuit using Integration Level Approximation

On-chip automatic tuning circuit with proposed integration level approximation technique, designed in a 0.65m 3.3V CMOS process for tuning of the variation passive component. To verify tunning efficiency of proposed circuit, three types of 2nd-order biquad RC active filters were used. The cut-off frequency (fc) error of filter with proposed tuning circuit can be reduced by new algorithm that co...

Area efficient circuit tuning with floating-gate techniques

An area efficient technique for tuning floatinggate circuits is described. The effective threshold voltage seen from a control gate can be programmed to virtually any value. The floating-gate transistor (FGMOS) may be used to implement low-power/low-voltage digital -and/or analog circuits.

an Efficient Drive Circuit for Switched Reluctance Motor

The purpose of this paper is to present an efficient converter circuit used to drive switched reluctance motors. It uses the C-dump topology in which the trapped energy in the phase windings is returned to the supply capacitor to be used in the following strokes. In addition to the C-dump topology, it uses two extra feedbacks. One comes from a governor mounted on the shaft of motor which contro...
