Abstract: A system and method for enhanced frequency measurement. Embodiments provide an effective mechanism for reducing error associated with frequency measurements by amplifying the frequency of the signal fed to the frequency counter, thereby increasing the number of counts and reducing the error associated with each frequency measurement. Reductions in error enable the gate time for the frequency counter to be reduced, thereby increasing efficiency and cost-savings. After accessing the counts provided for the amplified frequency, the original frequency before amplification may be determined by reducing the amplified frequency (e.g., represented by the accessed counts) by the amount by which the original frequency was amplified. Embodiments provide an effective and efficient mechanism for automatically determining the amount of amplification for a given signal based upon its frequency and a maximum frequency of at least one of the frequency amplification component and the frequency counter.

Abstract: Bandgap reference (BGR) circuits and methods are described herein for providing high accuracy, low power Bandgap operation when using small, low voltage devices in the analog blocks of the BGR circuit. In some cases, chopped input stabilization and dynamic current matching techniques may be combined to compensate for input voltage offsets in the operational amplifier portion and current offsets in the current mirror portion of the Bandgap circuit. When used together, the chopped stabilization and dynamic current matching techniques provide a significant increase in accuracy, especially when using small, low voltage devices in the analog blocks to reduce layout area and support low power supply operation (e.g., power supply values down to about 1.4 volts and below).

Abstract: An improved method of framing data packets in a direct sequence spread spectrum (DSSS) system that uses one pseudo-noise code (PN-Code) to frame the packet with a start-of-packet (SOP) and end-of-packet (EOP) indicator, and a different PN-Code to encode the data payload. Furthermore, the SOP is represented by the framing PN-Code, and the EOP is represented by the inverse of the framing PN-Code. This method creates a robust framing system that enables a DSSS system to operate with a low threshold of detection, thus maximizing transmission range even in noisy environments. Additionally, the PN-Code used for the SOP and EOP indicators can be used to indicate an acknowledgement response.
