摘要： Disclosed is a process control transmitter having an externally accessible DC circuit common that eliminates the need to perform level shifting of signals communicated between the transmitter and external processing electronics. The process control transmitter includes first, second and third terminals which feedthrough a housing. Circuitry contained in the housing is coupled to the first, second and third terminals and is adapted to communicate information to external processing electronics through the second and third terminals using a digital signal that is regulated relative to a DC common that is coupled to the second terminal. External processing electronics can couple to the second and third terminals and interpret the digital signal without having to perform level-shifting adjustments.

摘要： A static random access memory (SRAM) cell with single event and soft error protection using ferroelectric material is presented. The SRAM cell comprises two inverters in a mutual feedback loop, with the output of each of the inverters coupled to the input of the other. A ferroelectric capacitor is coupled to the output of one of the inverters in order to induce an RC delay and provide single event upset (SEU), single event effect (SEE), single event transient (SET), and soft error protection. In addition, a method is presented where ferroelectric capacitor of the system is fabricated after the underlayers of the SRAM cell have been implemented in order to avoid substantial changes to standard underlayer processing.

摘要： A process, voltage, and temperature (PVT) compensation circuit and a method of continuously generating a delay measure are provided. The compensation circuit includes two delay lines, each delay line providing a delay output. The two delay lines may each include a number of delay elements, which in turn may include one or more current-starved inverters. The number of delay lines may differ between the two delay lines. The delay outputs are provided to a combining circuit that determines an offset pulse based on the two delay outputs and then averages the voltage of the offset pulse to determine a delay measure. The delay measure may be one or more currents or voltages indicating an amount of PVT compensation to apply to input or output signals of an application circuit, such as a memory-bus driver, dynamic random access memory (DRAM), a synchronous DRAM, a processor or other clocked circuit.
