Thank you for your continued support. I want to clarify that I did not draw the schematic for the obsolete watchdog timer circuit, digital latch circuit, and clock circuit used to support the ADC. Instead, I focused on tracing the schematic for the amplifier section, which is the key part of the...
Hello KlausST,
I really appreciate all the help you've given me so far, and I'm sorry if my previous message came across as dismissive or critical. However, I still have some questions and concerns about the circuit, and I was wondering if we could discuss them further. The circuit block...
The 100 Ohm resistors are connected to capacitors to create a low-pass filter. However, the opposite ends of these capacitors are connected to a 2.5V voltage reference instead of ground, and it's uncertain whether this still constitutes a valid low-pass filter configuration. The voltage...
Hello everyone,
To understand transimpedance amplifiers in more detail. I reverse engineered an electronic card of a photodiode amplifier of a machine which was not working because machine was scrap and probably made in around 1992 and It had few cards in it and few cards were lost and...
Hello Klaus and everyone else,
I explain what I mean by meaningful output. I means the output is with noise and with fluctuation and no proper sense can be made by looking at the oscilloscope output at the last opamp. It amplifies no difference. Until I short the function generator ground with...
Hello everyone,
This is the actual circuit made on a PCB and I couldn't get any stable results out from this circuit I injected Sin wave on the input of this amplifier instead of photodiode and I experiment with different frequency from 20Hz all the way to 1Khz Vpp 20mV to 1Vpp, but I couldn't...
Hello everyone,
I wanted to experiment if I could drive an LED 3mm RED 1.8V forward bias voltage through a capacitor, so I connect function generator on HighZ on 5Vpp 300KHz connect it with different capacitors non-polar and polar and in series with resistor and a LED. All small non-polar...
Hello everybody,
On a circuit, there is a component soldered and I believe this is a resistor of 2 band...but I also noted it's inductance value. I could not found out any 2 band resistors on the internet and they usually starts from at least 3 and upto 5 bands. On automatic detection, MASTECH...
Make an array in your program LILO(Last In Last Out). When ever a button is pressed the number is stored into your array. The elevator will ultimately go to the highest number. Using array technique you can solve the problem. If you need more help let us know.

You can use precision amplifier like AD620 to achieve that, what I understand is that you need to amplify 130mV to 500mV signal(this means gain of 3.84) and amplify 1V to 10v signal(this means gain of 10)
In terms of semiconductor physics, transistor safe operating current range is given in the datasheet. If you take them further, a phenomenon known as thermal runaway will occur. It occurs due to heat up, the internal resistance starts to drop even more allowing more current to flow, before such...
As far as I remember.... I did exactly as Fvm instructed me to do keeping in mind the transient effect and time constants of the circuit. I remember about altering multisim DC analysis parameters. The end results were the same as observed before to me. Maybe numerical analysis is yet better to...
