Low Noise Broadband Operational Amplifier Circuit
The circuit can increase the operational amplifier 101's gain bandwidth product to 100MHz. The circuit's input noise will be reduced to 0.5 μV(frequency band is 10KHz, signal source internal resistance value is 600Ω). The circuit moves 101's input grade out of inner circuit and uses the capacitor C2 to compose positive feedback compensating circuit which will increase the slew rate by 30 times. (View)

High-precision Linear Amplifier Circuit
The circuit is used to detect sensor signal. The circuit consists of bridge, operational amplifier A1, bridge voltage supply amplifier A2,A3. The output voltage UR,UR' of A2,A3 have the same value and opposite phases. Their values are decided by the base voltage UR and output voltage UO. In the bridge, (1+δ)R4 stands for the resistance value of the temperature sensor. δ is the relative variable ratio.The circuit's linear distortion is not larger than 0.5%, which can be use as the temperature measurement interface in air data processing system. It can also be used to measure the non electrical quantity such as pressure, speed and flow rate. (View)

3W High-power LED Drive Circuit

3W High-power LED Drive Circuit
The high-power LED easy driver is the one used in the high-power white light, but the difference is that I here use the 3W LED. The circuit will input1.2v working voltage(high capacitance NI-MH battery).The current is about 1.4-1.8A, which has a poor efficiency of about 70%. If the 150Ω resistor is replaced by a 200Ω one, and the input current is reduced to 1.0-1.3A, then a little copper sheet of an area of 3 cm² should be added on that D882 for heat radiation. I used a diagonal plier to remove the head of D882(to reduce the volume), and then welded it on the copper sheet directly. (View)

Dual Track Loudspeaker Protection Circuit

Published:2011/7/18 0:46:00 Author:Sue | Keyword: Dual Track, Loudspeaker, Protection

The picture shows the dual track loudspeaker protection circuit. It is designed that the left and right tracks are working independently. In the picture(to take the left track for example), R2, C4 and VT2,VT3 compose starting delay circuit which can prevent the large starting current from shocking the loudspeaker. Component choice:We can choose Φ3mm high-brightness two-tone LED as LED. Because of the reason that LED has different working currents, so R5,R9 have adjustable parameters. At the same time, LED and current-limiting resistor R5,R9 are connected to relay RE1,RE2 in parallel, which can prevent inverse peak voltage and can prevent VT2,VT3,VT5,VT6 frombeing punctured. The best choice for C4,C9 is low-leakage tantalum capacitor. (View)
