Multi-Stage Amp Build

Need help on how i should start this and find the values for the input impedance buffer

• The amplifier should be powered by a single 12V supply
• The input impedance should be >1 MΩ
• The input stage should be an AC coupled FET source follower(Buffer)(2N7000 Transistor)
• The input voltage 110 (mVpp)
• The output stage should be a phase splitter giving two outputs which have 180o ±2 o relative phase shift
• The output impedance of the inverting output should be within 10% of your assigned spec. value
• Total gain should be within 0.5dB of your assigned spec
• The gains of the two gain stages should be within 1dB of each other
• Each output should have <0.5dB gain variation over the 50Hz to 10kHz range
• The two outputs should not differ by more than 0.2Vpp at 1kHz
• Both outputs should be AC coupled and measured across 1MΩ load resistors
• Only one transistor should be used in each stage (4 transistors in total)
• Gain stages should use BC547B npn transistors

Gain = 31dB
Output Impedance of inverting output (kΩ) = 2
