low noise

I am currently developing a low noise preamp for a new piezo sensor that should be used as a hydrophone. Since I am actually from the signal processing domain the topic was quite hard to get into for me. The sensor is relatively new and not well characterized. The only specifications I have are...

By dedicated voltage regulators i mean a voltage regulator per IC, even if they require the same voltage. for example this is my circuit : Here i use 3 voltage regulators to provide 3.3V reference to 3 different devices. my goal in mind being the isolation of noise that can find itself on...

I'm designing some audio-frequency instrumentation for my workbench and am using TL074s for most opamp requirements. One section requires microvolt measurements and noise is therefore an issue. It's often difficult comparing opamps on noise and other figures because they're often stated...
