Diode as a temperature compensation circuit for transistors
Both diodes and transistors are made of silicon. As the temperature T increases, the transistor Vbe decreases, ib=VCC-Vbe/R7+R5 ib increases...
Today I used the built-in phase-locked loop of FPGA to divide the frequency by 10M to provide the clock for ADS805 to do AD sampling, the waveform is 500khz, in order to reduce the clock overshoot and...
Tip: Tue Jul 19 13:22:38 2005: Driver does not support code coverage.The program can be downloaded into the chip, but it cannot be simulated and debugged online!The version is: IAR Assem××er for MSP43...
Dear senior masters, I am recently designing a low-noise preamplifier circuit. Since the signal of the signal source is relatively weak, between 100uV and 1mV, the input noise of the circuit is very h...
