Assignee:

Sarnoff Corporation - Princeton NJ

International Classification:

H01L 2701

US Classification:

257350, 257 59, 257 72, 257401

Abstract:

A pixel structure having at least one organic thin film transistor (OTFT) that minimizes gate-to-pixel capacitance. In one embodiment, a pixel structure provides a new transistor structure where an OTFT electrode on the data-line side of the transistor is extended or wrapped around three sides of the transistor relative to a pixel-side electrode. Thus, the pixel-side electrode can be made very small without reducing the effective width (and therefore on-current) of the transistor.

Assignee:

Sarnoff Corporation - Princeton NJ

International Classification:

H03F 3217

US Classification:

330251, 330207 A

Abstract:

A radio frequency (RF) pulse power amplifier biased with a relatively low supply voltage generates one or more RF pulses having a relatively large output power. The RF pulse power amplifier may be configured as a push-pull power amplifier operating in class D mode including first and second sections, balanced-to-unbalanced (balun) transformer, and a load resistor coupled across the output winding of the balun transformer. Each section has a current source providing bias current, a MOS transistor, and a pair of bipolar transistors. Each section receives its input digital signal at the MOS transistor, which acts as a current switch for a bias current from a current source. With a relatively small voltage change in response to the input digital signal, the MOS transistor switches the bias current between itself and a transistor pair used to drive the corresponding half (input winding) of the balun transformer.

Inventors:

Michael Gillis Kane - Skillman NJ, US

International Classification:

G09G 3/30

US Classification:

345 76, 345 82

Abstract:

A pixel circuit for an OLED element comprises first, second, third and fourth transistors wherein controllable conduction paths of the first and second transistors are connected for receiving a data signal current, and the control electrodes thereof are connected for receiving a select signal for being enabled thereby. The third and/or fourth transistors are connected for establishing a current in the OLED element responsive to the data signal current and the select signal. Capacitance may be provided by at least one of the transistors or by additional capacitance.

International Classification:

G11C 11/34

US Classification:

36518511, 365148, 365 94

Abstract:

A read-only memory (ROM) is disclosed that uses the presence or absence of linear passive electrical elements, such as resistors or capacitors, to encode zeros and ones, permitting a large-area ROM to be fabricated, possibly on a flexible substrate. The ROM includes a substrate, a plurality of row conductors insulated from each other and at least partially layered on a portion of the substrate; a plurality of column conductors insulated from each other and from the row conductors and at least partially layered above or below a portion of the plurality of row conductors, a plurality of amplifiers electrically connected to the column conductors, and at least one linear passive element attached between the row conductors and the column conductors. An amplifier connected to a column conductor has an input impedance much lower than the combined parallel impedance of the linear passive elements connected to that column, thus comprising a virtual ground, and is operable to output a first logical state when one of the linear passive elements is electrically connected between one of the row conductors and one of the column conductors, and operable to output a second local state when said one of the linear passive elements is absent between one of the row conductors and one of the column conductors. The resistive or capacitive arrays can be made into low-cost imagers if the resistors/capacitors are sensitive to electromagnetic radiation or mechanical pressure.
