Abstract: A communications receiver architecture characterized by a relatively low intermediate frequency (IF) and a polyphase filter. The receiver includes an input amplifier coupled to a carrier signal. Respective I and Q demodulators are coupled to the output of the input amplifier. A quadrature local oscillator (LO) generator provides respective LO_I and LO_Q inputs to the I demodulator and LO_Q inputs to the I demodulator and to the Q demodulator. The quadrature LO generator is driven by a phase-locked LO, and the LO frequency is such that an IF of, in one embodiment, approximately 1 MHz results. The I demodulator and Q demodulator outputs are applied through respective AID converters to a polyphase filter. The polyphase filter outputs are then processed by a digital I/Q demodulator. Although a low IF is not generally understood to promote the image rejection performance of a receiver, substantial image rejection is afforded by the polyphase filter, thereby enabling the receiver to be realized almost entirely as a monolithic integrated semiconductor device.

Abstract: Half duplex, Frequency Hopped-Spread Spectrum wireless transceivers (102), operating without a central controller, maintain time synchronization with the frequency hopping sequence for a period after transmission of a half duplex signal ceases. The wireless transceiver (102) operates their receivers (308) according to the RF frequency hopping sequence and schedule (200). The wireless transceiver (102) is then able to send a short transmission request to signal that it will start transmitting on the Frequency Hopping schedule (200) of the previously ceased transmission. A wireless transceiver (102) that was either the original transmitter or the original receiver is able to transmit this transmission request. A subset of time slots within the hopping schedule (200) can be optionally assigned to the original transmitter and original receiver to obviate collisions of the transmit request transmissions from both device at the same time.

Abstract: Methods, compositions and articles of manufacture involving soluble conjugated polymers are provided. The conjugated polymers have a sufficient density of polar substituents to render them soluble in a polar medium, for example water and/or methanol. The conjugated polymer may desirably comprise monomers which alter its conductivity properties. In some embodiments, the inventors have provided cationic conjugated polymers (CCPs) comprising both solubilizing groups and conductive groups, resulting in conductive conjugated polymers soluble in polar media. The different solubility properties of these polymers allow their deposition in solution in multilayer formats with other conjugated polymers. Also provided are articles of manufacture comprising multiple layers of conjugated polymers having differing solubility characteristics. Embodiments of the invention are described further herein.

Abstract: A ring oscillator circuit, such as a VCO, with a relatively high level of noise rejection for noise originating from both the voltage supply and ground. The ring oscillator circuit is composed of a plurality of differential delay circuits, each differential delay circuit generating a differential output signal that is a delayed (and preferably inverted) version of a differential input signal. ‘Each differential delay circuit includes first and second input transistors for receiving the differential input signal. Each differential delay circuit also includes first and second load transistors coupled in parallel with the respective first and second input transistors. Each differential delay circuit further includes a first current source coupled between the first input transistor and a first power supply terminal (e.g., a voltage supply terminal), a second current source coupled between the second input transistor and the first power supply terminal and a third current source coupled between the first and second input transistors and a second power supply terminal (e.g., a ground terminal). The first and second current sources reduce the coupling of noise from the first power supply terminal to the output. The third current source reduces the coupling of noise from the second power supply terminal to the output.

Next, portions of the first dielectric layer is etched back to form a spacer layer, and then a second dielectric layer is formed over the spacer layer. Thereafter, an insulating layer is formed over the second dielectric layer. Finally, the insulating layer is fully etched back to form a third dielectric layer.

Abstract: 4(3H)-X-7H-Pyrrolo[2,3-d]pyrimidines in which X is .dbd.O or .dbd.NH are prepared by treating a 6-amino-4(3H)-X-pyrimidine with a unsubstituted or substituted 1-nitroalk-1-ene to yield a 6-amino-4(3H)-X-pyrimidine which is substituted in the 5-position by a 1-nitroalk-2-yl group; (ii) converting the 5-(1-nitroalk-2-yl)-6-amino-4(3H)-X-pyrimidine to the corresponding 5-(1-oxoalk-2-yl)-6-amino-4(3H)-X-pyr-imidine; and (iii) removing the elements of water from the 5-(1-oxoalk-2-yl)-6-amino-4(3H)-X-pyrimidine to effect cyclization. A typical embodiment involves treating 2,6-diamino-4(3H)-pyrimidone with 1-nitro-4-(4-ethoxycarbonylphenyl)-1-butene to yield 1 -nitro-2-(2,6-diamino-4(3H)-oxopyrimidin-5-yl)-4-(4-ethoxy-carbonylphenyl)butane which is then treated sequentially with base and acid, without isolation of the intermediate aldehyde, to form 4-[2-(2-amino-4(3H)-oxo-7H-pyrrolo[2,3-d]pyrimidin-5-yl)ethyl]benzoic acid, a valuable known chemical intermediate for the preparation of N-[4-{2-(2-hydroxy-4-amino-7H-pyrrolo[2,3-d]-pyrimidin-5-yl)ethyl}benzoyl]glutamic acid.
