It's hard to find info comparing FETs to tubes because they typically aren't used in this manner. What I do know is that the voltage gain of a 12ax7 is like 30v and the amplification factor is 100. I have no idea how to calculate the voltage gain or amp factor for a transistor ...
in the cotrol algrithom, i arealdy changed the I_max value from 62.5 A to 250A.(you can calculate the gain and offset according to my circuit.) now the problem is when use the 0.002Ohm resistor the motor can run while the 0.0005Ohm resistor ...
Keep in mind that R3 is outside of the op amp loop. This means that the op amp’s feedback can do nothing to decrease the resultant output impedance. We can calculate and simulate (measure) this output impedance. Since we are assuming an ideal op amp here, the output impedance...
for example, if the low-pass filter is designed for 1KHz, the circuit will output signals under 1KHz full to near full strength. Signals greater than 1KHz will be greatly attenuated,
If the calibration operation is correctly performed the adjusted parameter accuracy is within half of the trimming step. The VREFBUF trimming operation needs the following steps to be completed: 1. Set median code value in the TRIM register and measure the VREFBUF output. 2. Calcu...
inverting input is at the same potential as the inverting input, so V = 0V. This is due to the high gain of the ideal Op Amp. When the output is at a level of a few volts, the differential input can be at a level of some tens of microvolts. Hence, V is very close to zero...
The reason for not making R2 higher is the current flows through the RL is an exponential function. The error will be much larger with higher R2 if using a simple linear equation to calculate inductance. I am not capable of handling equations that are not 1st order linear. ...
I have a query set to calculate units processed per hour by user. The query returns the correct numbers when I run it, however every time that I run it , it will ask for parameters for two fields and ...
Then, when I read an analog pin, I can calculate the actual voltage on that pin using: Value_volts = analogRead(A0) /1023 * Vref The Input Impedance of an Arduino ADC Pin The Arduino input impedance of an ADC (analog-to-digital converter) pin is specified as 100 megohms. It sounds ...
(back at Figure 1), if we remove V1, and replace it with a short circuit to ground and calculate the output voltage, and then we do the same with V2, the output voltage of the differential amplifier is the sum of both output voltages as they were calculated with each source separately...
