Problems solved by technology

Since analog circuits are not formed from truly independent blocks, changing one block of analog logic can force changes to every other block in the circuit
Furthermore, improvements in process technology occur so rapidly that application-specific designs often become obsolete before they are manufactured
Ultimately, analog circuits are neither fully reconfigurable nor fully programmable

Embodiment Construction

[0034] A description of example embodiments of the invention follows.

[0035] Wideband Signal Processing (WiSP) is an analog signal processing technique; that is, it implements programmable and executable analog computations over a bandwidth ranging from 50MHz to 20GHz or more. The fundamental basis of WiSP is the state variable theory which, when combined with CMOS deep submicron technology, enables the use of low frequency signal processing techniques down to micron and millimeter wavelengths. WiSP can be realized by complementary metal-oxide-semiconductor (CMOS), silicon-germanium (SiGe) technologies, and silicon-on-insulator (SOI) technologies.

[0036] Since the parameters of the state-variable machine can be set to 10-bit precision, WiSP has high precision. WiSP is also frequency agile (frequency agile), capable of spanning the entire frequency band as state-variable parameters (such as gain) change. For example, a state variable machine centered at a frequency of abo...

Abstract

Broadband analog radio-frequency devices can be used to create building blocks for scalable analog signal processors that operate over bandwidths of 50 MHz to 20 GHz or more. Example devices include integrators (transconductors), digitally controlled attenuators, buffers, and scalable summers implemented using deep sub-micron CMOS technology. Because the devices are implemented in CMOS, the ratio of trace / component size to signal wavelength is about the same as that of low-frequency devices implemented in printed circuit boards. Combining this scaling with high gain / high bandwidth enables implementation of feedback and programmability for broadband analog signal processing.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application No. 61 / 359108, filed June 28, 2010, and US Provisional Patent Application No. 61 / 304064, filed February 12, 2010. The entire teaching of the above application is hereby incorporated by reference. [0003] governmental support [0004] This invention is supported, in whole or in part, by the United States Military under Contract No. W911NF-08-C-0085. The Government has certain rights in this invention. Background technique [0005] Increases in signal bandwidth and data rates have spurred the development of new signal processing techniques to address the challenges associated with wideband signals. The increase in signal bandwidth also enables new applications, including active radio frequency (RF) identification (ID) based on ultra-wideband (UWB) technology in heterogeneous environments. In addition, increased signal bandwidth improves ranging accuracy, making wideband...
