differentail amplifier

Hi, I am a beginner in hardware design. Recently got a task to design a simple current measurement device. The device should have only 3 states: Current is lower than 10 mA Current is between 10 and 100 mA Current is higher than 100 mA For current measurement I am using a LM358N op amp in a...

Hello! I have done calculations for designing a differential amplifier (DA) with differential output. I simulate (using cadence ) the DA with the calculated values and perform the DC analysis of the circuit to inquire all the transistors are operating in saturation. However, I did not get all...
