Zero-bias Si backward diodes detectors incorporating P and B δ-doping layers grown by chemical vapor deposition
2009 Edition, December 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Backwards diodes are well suited for the passive detection of millimeter-wave radiation [1], as they operate at zero-bias, which reduces 1/f noise, thereby enabling simple operation and compact focal plane pixels with no extra bias control circuitry required....

PN Ranging Based on Noncommensurate Sampling: Zero-bias Mitigation Methods
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper proposes two methods to mitigate the zero-bias of noncommensurate sampling based code tracking loops to significantly improve the pseudo-noise (PN) ranging accuracy. For the compensation-based method, a set of algorithms are developed to directly calculate the...
