Source follower amplifier. (a) Circuit schematic. (b) Block diagram representation of source follower output. The fundamental harmonic is a low-pass filtered version of the input. The second order terms are generated by high-pass filtering the input, squaring and then low pass filtering. The total output is a power series of ϵ terms.
