Introduction – Because of their typically fast edge rates, crystal oscillators can generate a large number of high-order harmonics. Figure 1 indicates a generalized trapezoidal digital signal. The ...

Many applications call for wide-range-tunable LC oscillators that can deliver a nearly constant-frequency, nearly harmonic-free output even when the circuit's output load changes. From a design ...

The weak link consists of a rectangular array of 24 slit-apertures of dimensions 3 µm by 0.17 µm each, separated by about 10 µm and made in a 0.15-µm-thick membrane. An array of slit-apertures was ...
