2 decade bjt and op amp design circuit
please show me the circuit of "Two decade BJT-OP AMP cascade inverting voltage amplifier".
SPECIFICATION:
only one BJT,One OP AMP UA 741 and a single power supply of 12v must be used.
a 10K ohm load and an input signal will be connected via capacitors to the amplifier.The maximum voltage gain is about -500. Input impedance is about 600 ohm.output impedance is about 10K ohm.The low cutoff frequency is about 200Hz and the high cutoff frequency is about 20KHz (bandwidth of 200-20Khz:2 decades).
The maximum peak-peak(MPP) output without clipping is ≥6v.The op amp must not produce a low rate distortion at ≤20KHz
