Source-free wireless micromechanical switch array control system

Abstract

The invention discloses a source-free wireless micromechanical switch array control system which comprises a signal source (1), a transmitting coil (2) and a source-free wireless micromechanical switch array unit (4), wherein the signal source (1) is connected in series with the transmitting coil (2); the transmitting coil (2) is in near-field coupling with the source-free wireless micromechanical switch array unit (4); the source-free wireless micromechanical switch array unit (4) comprises a plurality of source-free wireless micromechanical switch units (3) arranged in an array manner; the resonant frequencies of all switch units in the array of the source-free wireless micromechanical switch units (3) are designed to be different, therefore, in the array of the source-free wireless micromechanical switch units (3), the switching of each switch is controlled through the specific output frequency of the signal source.

Description

technical field [0001] The invention relates to a switch control system, in particular to a passive wireless micromechanical switch array control system. Background technique [0002] The switch can be used to control the on-off of the signal, and the switch array control system is an array composed of switches to selectively control multiple groups of signals. The switches used in the circuit mainly fall into two categories: mechanical switches and semiconductor switches. The advantage of the mechanical switch is that its off-state signal leakage is very small, and the disadvantage is that it is generally large in size and the switching delay is long; the advantage of the semiconductor switch is its small size, small switching voltage and delay, but its disadvantage is the off-state leakage voltage larger. Therefore, the switch array control system can be either a semiconductor switch array or a mechanical switch array. [0003] The passive wireless switch array means th...

Problems solved by technology

The advantage of the mechanical switch is that its off-state signal leakage is very small, and the disadvantage is that it is generally large in size and the switching delay is long; the advantage of the semiconductor switch is its small size, small switching voltage and delay, but its disadvantage is the off-state leakage voltage larger

Since the execution voltage of the micromechanical switch is relatively high, generally greater than 30V, the existing methods of controlling the on-off of the micromechanical switch are all wired.
