Wide-range oscillator with digital control for digital waveform generation
Electronics Letters, 1991 A variable frequency oscillator with precise digital control over a very wide frequency range has been developed. Two standard VCO chips are used to form two independent phase-locked loops; one adjusted to cover the lower frequency range and the other the higher frequency range.

Advanced Optical Materials, EarlyView.Intramolecular bridge‐locking frustrates detrimental anti‐parallel packing in evaporated organic films. This design enhances net polar orientation, leading to a twofold off‐resonance increase in the second‐order nonlinear susceptibility (χ(2)) without electric‐field poling.
