Hi all
i want to design a low noise preamplifier for a data sample collector.
and the signal from the sensor is very very samll,in order to prevent the usefull signal from swampped by the noise made by the circuit itself i need to design a low noise preamplifier circuit to amplify the signal.
so how should i choose the component for the amplifier.
what kind of operatinal amplifier i must choose??
what kind of component i should choose,BJT,JFET or CMOS??
Thanks~~~~~~~~
