1. The responses of the abdominal and pleural giant cells to warming and cooling were studied using constant-current and constant-voltage techniques. 2. The potential change upon warming from about 7 degrees C to 22 degrees C was reversed by application of maintained inward current. The reversal potential was -77 +/- 12 mV. 3. The membrane conductance increased with warming, but was not affecte...

Three-phase shunt active power filter (APF) is often used to compensate the harmonic and reactive current derived from non-linear load. But many non-ideal factors, such as the limited bandwidth of output current loop and the time lag of signal sensing circuit and reference current generation etc, will deteriorate the compensation effect. Proportion-Integral (PI) controller cannot be used simply...

The Resistance Spot Welding (RSW) process requires simultaneous application of high electrical current and appropriate pressure over short periods in order to keep the molten material inside the weld zone. Values of these parameters vary in function of the characteristics of the materials to be welded. The application of the electrical current is by means of two copper electrodes brought in con...

In Analog circuit design field, current reference circuit is mostly used for constant current supply to the circuits, so that their function runs properly. This work gives a circuit that operates with minimum operating voltage and current, CMOS current generator circuit and presents its performance with circuit simulation in 180nm UMC CMOS technology. The designed circuit has four sub parts sta...
