The following is a common input and feedback structure in audio power amps: simulate this circuit – Schematic created using CircuitLab What I often see is that the resistors are chosen ...
I have a wave profile stored in a micro-controller that I want to scale and shift with two input arguments. Is it possible to fix an 'absolute' scale (max/min = 1.02 for e.g.) and have an offset that ...
I have this thermocouple conditioning circuit. Let's say my gain is 100. Minimum low level for AD8237 is 20mV. As K type thermocouple outputs 40uV per 1C, I will have 4mV per 1 degree C. This ...
Not all opamps have explicit offset-null support, but all opamps have offset voltage. This is exactly my practical circuit: How do I correct offset voltage of TL084 in this circuit? (Datasheet: ...
I have a square wave being generated from a waveform generator oscillating between 0 V and 5 V. The generator does not support negative DC offsets. I need to shift this signal down to be centered ...
I am trying to create a circuit which will allow me to scale and offset a voltage (be it AC or DC) to within the range of the Arduino ADC. The voltage could be anything between + and - 250V, but I ...
