< Mentor Note -- thread moved to HH from the technical engineering forums, so no HH Template is shown > Hi, I have a task to create a two-stage amplifier without feedback. It shall be made with these requirements; It shall be connected to a source of internal resistance equal 2.2kΩ and a load of 1kΩ. Create amplifier so that these requirements are met: • Voltage Gain at medium frequencies = 100 ± 10% • input resistance ≥ 20kΩ • Lower limit frequency ≤ 50Hz • Quite linear • Working point is stable • Power draw should be ≤ 10mA The input signal amplitude is less than or equal to 20mV. The supply voltage is 15V. As showen in the picture the type of transistor is: BC546B, so its possible to find the beta value (Typ 290). I want to find the value of the ressistors and capacitors, to meet thise requirements above. What is the first thing i should find out, with these requirements? How should I start?
