Design considerations for MMIC distributed amplifiers
(IEEE, 1994)
The bandwidth of the input artificial line in a distributed amplifier is the main band limiting factor. By choosing this impedance properly the bandwidth of a distributed amplifier can be maximized. A four section GaAs ...
Hybrid atomic force/scanning tunneling lithography
(American Vacuum Society, 1997)
We present a new technique for performing lithography with scanning probes that has several advantages over standard methods. This hybrid lithography system combines the key features of the atomic force microscope (AFM) ...
Two-dimensional micromechanical bimorph arrays for detection of thermal radiation
(American Institute of Physics, 1997-06-16)
We demonstrate that two-dimensional arrays of micromechanical bimorphs can be used as thermal sensors to image infrared (IR) radiation. A density of 100 pixels per mm2 is achieved by coiling a bimorph beam into the shape ...
Analytic modeling of loss and cross-coupling in capacitive micromachined ultrasonic transducers
(IEEE, Piscataway, NJ, United States, 1998)
The structural loss mechanism of capacitive micromachined ultrasonic transducer (cMUT) is investigated using finite element analysis and the normal mode theory. A single micromachined transducer membrane on an infinite ...
Design and implementation of a general-purpose median filter unit in CMOS VLSI
(IEEE Solid-State Circuits Society, 1990)
A general-purpose median filter unit configuration is proposed in the form of two single-chip median filters, one extensible and one real-time. The networks of the chips are pipelined and systolic at bit level and based ...
An efficient program for analysis of interconnect circuits
(Taylor & Francis, 1997)
A circuit simulation program using generalized asymptotic waveform evaluation techniques is introduced. The program analyses circuits with lumped and distributed components. It computes the moments at a few frequency points, ...
Anisotropy sensitivity of an acoustic lens with slit aperture
(IEEE, 1993)
A conventional spherical acoustic lens is modified by restricting its aperture in the form of a slit to provide directional sensitivity. The spacing between the two parallel absorbing sheets forming the slit is adjustable ...
Dual integrated actuators for extended range high speed atomic force microscopy
(A I P Publishing LLC, 1999-09-13)
A flexible system for increasing the throughput of the atomic force microscope without sacrificing imaging range is presented. The system is based on a nested feedback loop which controls a micromachined cantilever that ...
Nanometer-scale patterning and individual current-controlled lithography using multiple scanning probes
(A I P Publishing LLC, 1999-06)
Scanning probe lithography (SPL) is capable of sub-30-nm-patterning resolution and
nanometer-scale alignment registration, suggesting it might provide a solution to the semiconductor
industry’s lithography challenges. ...
A VLSI receive beamformer for digital ultrasound imaging
(IEEE, 1992-03)
A VLSI architecture for real-time digital receive beamforming in phased array ultrasound imaging is proposed. The architecture is an inverse binary tree like structure with N stages where N is the number of array elements. ...
