Abstract

1277614 Electrostatic resonators STANDARD TELEPHONES & CABLES Ltd 5 March 1970 [7 March 1969] 12218/69 Heading H3U An electromechanical resonator comprises one or more vibrator elements 1 vibratable by electrostatic forces between itself and an electrode 2. In Fig. 1, the element 1 is fixed at one end to a support 3, and an A.C. input signal is applied from G1. Electrostatic forces cause the element 1 to vibrate, and an output appears across the load R3-C out due to charge flowing in and out of the capacitance formed by the element 1 and electrode 2. To prevent frequency doubling the element 1 is biased by battery B1 through a high resistance R1, a capacitor C E decoupling the bias. Because the electrostatic forces between the element 1 and electrode 2 depend on the square of the potential between them, the bias causes voltage gain. The resonant frequency of the system is determined by the dimensions and material used for the element 1 and by air damping, the latter being eliminated if necessary by perforating the element or by evacuating the surroundngs. The resonator may be operated up to a few hundred KHz, though the preferred range is 1-30 KHz, and its dimensions are submillimetric. Various combinations of such resonators are possible, e.g. a single element with separate input and output electrodes, Figs. 4-7 (not shown). Several resonators may be interconnected, either by mechanically linking the vibrator elements, Figs. 10, 11 (not shown) or by linking them electrically, Figs. 9, 12 (not shown), or by both methods. The electrodes may be electrically interconnected. Such combinations allow the passband to be tailored as required, Fig. 15 (not shown). The bias used may be applied to either the vibrator elements or the electrodes, and may be D.C. or A.C., the latter giving a modulator action. The elements, which may be strips, rods, discs or rings may be supported at any nodal point or points, not necessarily at the end. The resonator may be used as a filter, or as a transformer, and is suitable for a hybrid integrated circuit.
