FIG. 1.

Schematic of half-wave and full-wave rectification of a sinusoidal time-dependent input voltage.

FIG. 2.

Solutions for uniform amplitudes. (a) The probability density function for scaled voltage (  ≡ 1) for a varying number of frequency components. By  = 5, the result is almost indistinguishable from the asymptotic limit. (b) Rectification efficiency (solid circles) as a function of . The limiting values of 8/π for  = 1 and 2/π for → ∞ () are indicated by the dashed lines.

FIG. 3.

Illustration of cascaded full-wave rectification (limited to two stages for illustrative purposes). The graphs show the full-wave voltage of the first stage (solid red curves), the corresponding second-stage signal from which the DC component output of the first stage has been removed (dashed blue curves), and the DC values of both (horizontal dotted lines). (a) For a single unit-amplitude sine wave ( = 1). The DC output of the first stage is simply the average of the sine function, 2/π. (b) Scaled voltage (  ≡ 1) for a broadband incoherent signal ( → ∞) with constant amplitudes. As noted in Eq. (7) , the DC output of the first stage is √(2/π).
