Experimental results show that bipolar, field-effect, and monolithic preamplifiers can be built with a sensitivity of 50 nanovolts per root hertz, or better, at 1000 hertz. Such preamplifiers will amplify extremely low signals generated by infrared detectors and similar units, and will keep system noise to a minimum at the same time. A sensitivity of 10 nanovolts per root hertz at 1000 hertz can be achieved with the use of the monolithic preamplifier. Author
