Abstract: An embodiment pulse generator circuit comprises a first electronic switch coupled between first and second nodes, and a second electronic switch coupled between the second node and a reference node. An LC resonant circuit comprising an inductance and a capacitance is coupled between the first and reference nodes along with charge circuitry comprises a further inductance in a current flow line between a supply node and an intermediate node in the LC resonant circuit. Drive circuitry of the electronic switches repeats, during a sequence of switching cycles, charge time intervals, wherein the capacitance in the LC resonant circuit is charged via the charge circuit, and pulse generation time intervals, wherein a pulsed current is provided to the load via the first and second nodes. The charge and pulse generation time intervals are interleaved with oscillation time intervals where the LC resonant circuit oscillates at a resonance frequency.

Abstract: A semiconductor detector of gravitational waves of a first frequency may include an oscillator having a metal coated oscillating member over a metal coated semiconductor substrate to be subjected to a Casimir attraction force towards the semiconductor substrate. The oscillator may be configured to exert a force to counterbalance the Casimir attraction force causing the oscillating member oscillates with a main harmonic resonance frequency equal to the first frequency. A displacement sensor may be coupled to the substrate and oscillating member and configured to sense oscillations and to generate corresponding sense signals. A pass-band filter may be tuned to the main harmonic resonance frequency and configured to generate band-pass replica signals of the sense signals, and an airtight package may be configured to keep a vacuum between the oscillating member and the semiconductor substrate. An array of semiconductor detectors and a method of detecting gravitational waves are also disclosed.
