Noise analysis of geometrically complex mechanical structures using the analogy between electrical circuits and mechanical systems
(A I P Publishing LLC, 1999-05)
Random fluctuations of displacement or velocity in mechanical systems can be calculated by using the analogy between electrical circuits and mechanical systems. The fluctuation-dissipation theorem expresses the relation ...
Application of asymptotic waveform evaluation for time-domain analysis of nonlinear circuits
(Taylor & Francis, 1997)
A method is described to exploit asymptotic waveform evaluation (AWE) in the time-domain analysis of nonlinear circuits by using SPICE models for nonlinear devices such as diodes, transistors, etc. Although AWE has been ...
An electrical circuit theoretical method for time-and frequency-domain solutions of the structural mechanics problems
(John Wiley & Sons Ltd., 1999)
Shrinking device dimensions in integrated circuit technology made integrated circuits with millions of components a reality. As a result of this advance, electrical circuit simulators that can handle very large number of ...
Pole-zero computation in microwave circuits using multipoint Padé approximation
(Institute of Electrical and Electronics Engineers, 1995-01)
A new method is proposed for dominant pole- zero (or pole-residue) analysis of large linear microwave circuits containing both lumped and distributed elements. The method is based on a multipoint Padé approximation. It ...
A new method for nonlinear circuit simulation in time domain: NOWE
(Institute of Electrical and Electronics Engineers, 1996-03)
A new method for the time-domain solution of general nonlinear dynamic circuits is presented. In this method, the solutions of the state variables are computed by using their time derivatives up to some order at the initial ...
Micromachined two-dimensional array piezoelectrically actuated transducers
(A I P Publishing LLC, 1998-03-16)
This letter presents micromachined two-dimensional array flextensional transducers that can be used to generate sound in air or water. Individual array elements consist of a thin piezoelectric ring and a thin, fully ...
Automated parallel high-speed atomic force microscopy
(A I P Publishing LLC, 1998-05-04)
An expandable system has been developed to operate multiple probes for the atomic force microscope in parallel at high speeds. The combined improvements from parallelism and enhanced tip speed in this system represent an ...
Analysis and design of an interdigital cantilever as a displacement sensor
(A I P Publishing LLC, 1998-06-15)
The interdigital (ID) cantilever with two sets of interleaving fingers is an alternative to the conventional cantilever used in the atomic force microscope (AFM). In this paper we present a detailed analysis of the ...
High‐speed atomic force microscopy using an integrated actuator and optical lever detection
(A I P Publishing LLC, 1996-09)
A new procedure for high‐speed imaging with the atomic force microscope that combines an integrated ZnO piezoelectric actuator with an optical lever sensor has yielded an imaging bandwidth of 33 kHz. This bandwidth is ...
Theory and analysis of electrode size optimization for capacitive microfabricated ultrasonic transducers
(Institute of Electrical and Electronics Engineers, 1999-11)
Theoretical analysis and computer simulations of capacitive microfabricated ultrasonic transducers indicate that device performance can be optimized through judicious patterning of electrodes. The conceptual basis of the ...
