I need a good,low distortion preamplifier topology. The parameters it must obey are input voltage 350mv Ueff, output voltage 900mv Ueff (around 3 times gain) its output impedance should be 2,2Kohm and it must operate at 12V because I have an lm7812 which ive been meaning to utilise. Given the stability it offers a pretty low noise will be introduces from the power supply itself.
