(a) The ratio of Johnson noise to Hooge noise varies fmax and the operating constraints but remains on the order of unity in order to maximize the benefit of the two noise sources being uncorrelated. (b) The noise power spectral densities for the three optimized cantilever designs for fmax equal to 1, 10, and 100 kHz. The amplifier noise is an order of magnitude less than the piezoresistor noise at all frequencies.
