Abstract: The invention relates to an improved K-Delta-1-Sigma Modulators (KG1Ss) that achieve multi GHz sampling rates with 90 nm and 45 nm CMOS processes, and that provide the capability to balance performance with power in many applications. The improved KD1Ss activate all paths when high performance is needed (e.g. high bandwidth), and reduce the effective bandwidth by shutting down multiple paths when low performance is required. The improved KD1Ss can adjust the baseband filtering for lower bandwidth, and can provide large savings in power consumption while maintaining the communication link, which is a great advantage in space communications. The improved KD1Ss herein provides a receiver that adjusts to accommodate a higher rate when a packet is received at a low bandwidth, and at a initial lower rate, power is saved by turning off paths in the KD1S Analog to Digital Converter, and where when a higher rate is required, multiple paths are enabled in the KD1S to accommodate the higher band widths.

Abstract: The invention is a radiation hardened charge-pump system and method of using polysilicon diodes and metal-to-metal capacitors in a standard CMOS process technology that provides boosted positive or negative voltages higher than power supply voltage levels, that reduces or eliminates field leakage, bipolar snap-back, SEL problems, and the SEGR problem. The charge-pump system is arranged as multiple parallel redundant pumps to harden the circuit so that if there is a single-event transient, or an unknown polysilicon-diode failure in a new technology, the remaining pumps will continue to operate. A diode placed at the end of each redundant pump section allows charge to be placed onto the high voltage node without removing charge due to failure of one of the sections. With the use of auxiliary circuits, such as a voltage doubler, this hardened charge pump can be used reliably at low power supply voltage levels.

Abstract: A radio frequency transceiver system is used for communications among the crewmembers of an aircraft, either inside or immediately outside. Aside from employing analog and digital circuits, the system utilizes Frequency Hopping Spread Spectrum (FHSS), Digital Spread Spectrum (DSDS), Time Division Duplex (TDD) or Time Division Multiple Access (TDMA) as to provide reliable and secure communications contact, regardless of adverse weather conditions, handling or operating stresses, or other conditions which would otherwise affect transmissions as in prior art devices. The system virtually eliminates interconnect aircraft cable damage; operational delays caused by missing cables, or broken cables; and delays or malfunctions resulting from having cables of the wrong size, length, weather resistance, etc. Since a crewmember has no interconnecting aircraft cable, this system allows greater freedom of moment about the aircraft, and crewmembers can no be inadvertently tripped, or lose balance.
