Abstract
Official abstract text for this publication.
A multiple frequency reconfigurable voltage controlled oscillator (VCO) ( 136 ) includes a variable capacitance device ( 112 ), an inductor ( 116 ) coupled in parallel with the variable capacitance device ( 112 ), and at least two circuit paths ( 118, 120, 122 ) coupled in parallel with the variable capacitance device ( 112 ) and the inductor ( 116 ). The circuit paths ( 118, 120, 122 ) each include a piezoelectric laterally vibrating resonator ( 126, 130, 134 ) and a switch ( 124, 128, 132 ) for selectably coupling each piezoelectric laterally vibrating resonator ( 126, 130, 134 ) in parallel with the inductor ( 116 ) and variable capacitance device ( 112 ).
First claim
Opening claim text (preview).
What is claimed is: 1. A multiple frequency reconfigurable voltage controlled oscillator (VCO) comprising: at least one resonator, wherein the at least one resonator is a piezoelectric laterally vibrating contour mode micro-electro-mechanical systems (MEMS) resonator, the at least one resonator comprising a first resonator and a second resonator, wherein the first resonator in the at least one resonator is tunable by about fifteen percent in either direction, and wherein the secon…
