Hall sensor quiescent voltage to zero - Physics Forums
2009年6月4日 · Hall sensor quiescent voltage to zero. In summary, the conversation discusses a Hall sensor that outputs 2.45 volts without a magnetic field and changes with the application of a magnetic field. The person needs to measure the voltage from zero and plans to use a Picaxe chip with 10-bit A to D converters.
Do transistors only work with DC and not with AC? - Physics Forums
2019年2月14日 · So it is indeed true that transistors work only with DC signals. You should probably try to be a bit more accurate in the terminology. "DC" usually means a unipolar non-varying current. Whereas "AC" means that the current is alternating (usually about some quiescent current value, as Jim has pointed you to).
Analyzing the internal circuitry of IC 741 Op-Amp step by step
2021年9月25日 · Q16, Green, is biasing to set the output stage (Q14, Q20) quiescent current, eliminating crossover distortion, probably class AB. (Enter the circuit in a simulator such as the free LTSpice to see all the bias points.) The Output current limiting is …

Calculate impedance of a feedback circuit with Blackman's technique
2015年7月21日 · Thanks for your research! Only thing I would point out is that g m is a strong function of V gs = 0.1AV where V is the quiescent + amp input voltage ("point 1"). So the operating point of the circuit still has to be solved for, then g m = 2k(0.1AV - V T) can be determined. Of course, you'd need k also.
Confusion about Wave Motion - Physics Forums
2024年9月24日 · The same effect that causes distant sound, radio, and light to be weaker with distance; i.e. the increasing size of the wavefront with distance. distributed over a steadily increasing area or volume. This happens for 2 and 3D waves but, for a linear wave, the energy stays within the region of a wave as it travels.
rsions of the GFA-5400 amplifier. The primary difference between the original version 1 and the updated version 2 is the addition of the ADCOM outp. t protection circuit in version 2. This circuit can be noted by comparing the schemati. of both versions in this manual. The protection circuit in version 2 includes trigger ICs IC711 and IC712 and ...
