The circuit diagram of a power MOSFET amplifier circuit with high frequency feature

Published:2011/7/13 19:49:00 Author:leo | Keyword: Power MOSFET amplifier, high frequency

The picture 1 is a power MOSFET amplifier circuit with high frequency feature. In order to restrain the influence of the changes of power supply, it takes VT1 and VT2 to form the constant current circuit，while, VT3 and VT4 are end power amplifying circuit. Due to the influence of offset current, its drain currenthastemperature factors which is from positive to negative. Therefore, it uses RP2 to control the offset in order to set the drain current to 0.1 to 0.2 A, which passes through VT3 and VT4. And when its frequency is 1Hz to 800 kHz, the distortion is 0.04% per 1 kHz. At the same time, its output power is 40 W and the convert rate is 100V/μs.   (View)

A differential test circuit made by analog switch

Published:2011/7/13 19:55:00 Author:leo | Keyword: Test circuit, Analog switch

What the picture shows is a differential test circuit made by analog switch. In the circuit, sensor uses hall component H. When magnetic field is imposed vertically on hall component H, the control current value between a and b is l1, then the hall voltage produced is KBI1 plus UB. In this formula UH=KBI1+UB, k is the proportionality constant, UB is unbalanced voltage. In order to clear this unbalanced voltage, we can make the average of the control current I1 of this hall component equal to zero. We can do this by using switch s10 and s20 to convert the control current I1 alternately to make the amplitude of vibration equal to the time at the moment. At the same time, to make the hall component have a steady sensibility, we only need to make the control current I1 steady. Control current is decided by Ur and Rs, that is I1=Ur/Rs.   (View)
