Dear all,
Grateful if you may advise on idea for designing a very low noise
pre-amp for ultrasonic sensor application.
Input 0.01mV
Output 3 volts
Freq 1 kHz to 100KHz with reasonably flat response
How should I choose between:
a) bi-polar transistor
b) Junction FET
c) MOS FET
d) low noise OP-Amp
Would it be right to presume that discrete transitor (bipolar, jfet or
mosfet) amplifier will have lower noise since it can be designed with
about 3 stages with 3 transistors instead of an OP-Amp which contains
tens of transistors?
Any software design tools or books or web pages on the topic?
Thanks in advance
Simon
