The present invention relates to an electronic device comprising a printed substrate comprising a trace of molecular ink thereon, the molecular ink being sintered to form a conductive metal trace forming the electronic device, wherein the molecular ink is chosen from a) a flake-less printable composition of 30-60 wt % of a C-Csilver carboxylate, 0.1-10 wt % of a polymeric binder and balance of at least one organic solvent, all weights based on total weight of the composition; or b) a flake-less printable composition of 5-75 wt % of bis(2-ethyl-1-hexylamine) copper (II) formate, bis(octylamine) copper (II) formate or tris(octylamine) copper (II) formate, 0.25-10 wt % of a polymeric binder and balance of at least one organic solvent, all weights based on total weight of the composition.

Printed electronics

An electronic component such as a voltage controllable reconfigurable capacitor or transistor is formed by printing one or more layers of ink on a non-conductive substrate. Ferroelectric ink or semi-conductive ink is printed and conductive resistive or dielectric ink is printed on a s same or different layers. Reconfigurability is achieved by printing resistive biasing circuitry wherein when a changing voltage is applied to the biasing circuitry, an electronic property of the electronic component changes in response to the changing voltage.

Printed reconfigurable electronic circuit

A standing wave oscillator includes a cross-coupled differential transistor pair having a pair of input terminals and a pair of output terminals; and a resonant circuit coupled to the input terminals of the cross-coupled differential transistor pair. The resonant circuit includes: a capacitance between the input terminals of the cross-coupled differential transistor pair; and a differential dual-mode coplanar waveguide (CPW) having opposite differential ends thereof connected to respective input terminals of the cross-coupled differential transistor pair. CPW ground lines of the differential dual-mode coplanar waveguide each have a first end thereof connected to the first supply voltage and have a second end thereof floating or unterminated.

A capacitively loaded multilevel transmission line network for operation at a microwave frequency f is disclosed wherein microstrip conductors are disposed over or under a uniplanar transmission line (UTL), electrically connected thereto at or near opposing ends of the UTL and coupled to portions of the UTL separated therefrom by a thin dielectric film. The microstrip conductors and the portions of the UTL coupled thereto form thin-film microstrip (TFMS) shunt stubs capacitively loading the ends of the UTL for increasing its electrical length. The present invention enables considerable size reduction of microwave circuits having uniplanar transmission lines.
