IPC: H03K3/354
Filed: 1990-02-13
Abstract: A CMOS ring oscillator includes an odd number of serially connected inverter stages with each stage comprising a CMOS transistor pair (26, 28). The output of each stage is taken at the common terminal of the CMOS transistor pair (26, 28) with capacitive means (30) shunting the output of each stage to circuit ground. The input of each stage is applied at the gate of the p-channel transistor (26). A fixed reference voltage, V REF , is applied to the gate of each n-channel transistor (28), whereby the discharge of voltage on the capacitive means (30) through the n-channel transistor (28) is independent of supply voltage.

Abstract: Prior art methods for quantitation of radioisotopically labeled molecules employ isotopes emitting a single electron, positron or gamma-photon. Their sensitivity is limited by background events which cannot be distinguished from the decays of the isotopic label. There are isotopes decaying with concurrent production of a positron and a gamma photon, with a subsequent positron-electron annihilation producing paired 511 keV gammas with opposite momenta. The Coincident Gamma-photon Detector (CGD) registers a count when coincident gamma-photons of known energies are detected. When set to the triple gamma signature of a particular isotope, the CGD achieves exceptional background rejection with resultant improved capacities to quantitate minute traces of the isotope. With the increased sensitivity thus achieved, there are advantageous novel uses of the multiple gamma producing isotopes, for the quantitation of molecules in which they can be incorporating or adducted to.

Abstract: Disclosed is a dual priority switching apparatus for making input port to output port connections on a requested basis quickly and dynamically, in a standard mode from any one of the input ports to any one of the output ports, in a multi-cast mode from any one of the input ports to a fixed number of subsets of multiple output ports simultaneously, or in a broadcast mode from any one of the input ports to all output ports simultaneously, using a new high priority approach to resolve either broadcast or multi-cast contention amongst input ports. The disclosed priority broadcast and multi-cast functions provide a more complex, yet faster and higher powered broadcast and multi-cast function. The disclosed invention permits multiple broadcasts to be queued at the individual switching apparatus which resolves the broadcast contention on a synchronous priority driven basis that permits one broadcast to follow the other at the earliest possible moment and the quickest possible speed. In addition, the present invention permits multiple multi-cast operations to occur simultaneously within in the network. This is becoming an increasingly important function for future massively parallel processors consisting of many nodes that can be subdivided into many tasks. The multi-cast function permits subsets of nodes assigned to the same tasks to communicate amongst themselves without involving other nodes that are not in its own subset. The present invention provides a network capable of sustaining many multi-casts simultaneously, thus, providing a very powerful tool for future parallel applications. In accordance with our inventions, we provide hardware circuitry for the detection and correction of deadlock conditions in the multi-stage network. Deadlock conditions are not expected to be usual conditions in the network, but there is a possibility of their occurrence resulting from multiple simultaneous broadcasts or multi-casts colliding within the network in a manner which is not resolvable. The hardware circuitry detects all the different types of deadlock conditions automatically and issues correction indications to the network paths involved. The network deadlock is thereby eliminated, and the two broadcasts or multi-casts involved continue their operation in a rearranged sequence that will not cause deadlock.

Abstract: The present invention provides a high frequency CMOS voltage controlled oscillator circuit with gain constant and duty cycle compensation. The voltage controlled oscillator circuit includes a multi-stage ring oscillator that includes a plurality of series-connected inverter stages comprising N-channel and P-channel transistors. The ring oscillator responds to a control current signal for controlling the frequency of oscillation of the ring oscillator. A voltage-to-current converter converts a tuning voltage input signal to a corresponding output current signal that is independent of the channel strength of the N-channel and P-channel transistors. Process compensation circuitry responds to the tuning voltage input signal to provide a current dump output signal corresponding to the channel strength of the P-channel and N-channel transistors. Trip-point compensation circuit provides a net ring current signal as the current control signal to the ring oscillator. The net ring current signal represents the difference between the output current signal and the current dump output signal and responds to the balance between the output buffer trip point and a ring oscillator dummy stage.
