A universal CMOS current-mode operational amplifierBotelho, Cindy 19 December 1990 (has links)
It has become customary in electrical engineering to think of
signal processing in terms of voltage variables to the exclusion of
current variables. This tendency has resulted in voltage signal
processing circuits such as voltage-controlled voltage sources
(VCVS) and voltage-mode operational amplifiers. However, the VCVS
operational amplifier has several limitations which prevent high
performance operation. One of these limitations is that the product
of the closed loop -3dB bandwidth and the closed loop voltage gain is
approximately a constant. Thus, for a typical internally compensated
operational amplifier the closed loop -3dB bandwidth decreases as
the closed loop voltage gain increases. By taking advantage of a
current-controlled current source (CCCS) to form a current-mode
operational amplifier, this limitation can be overcome. / Graduation date: 1991

Opamp characterization techniquesRamamurthy, Karthik 22 June 1993 (has links)
Standard methodologies exist for testing and characterizing digital circuits but the
same cannot be said of analog circuits. Though much theoretical work has been done to
model the linear and nonlinear aspects of analog circuits, a firm practical background for
the design of testable analog cells has yet to be set. The industry largely looks for solutions
wherein some form of built in self-test (BIST) can be incorporated into the analog circuits
to make the testing at the manufacturing level easy and accurate. Since the testers in the
industry are generally digital, test circuits that use logic levels at the output to make
measurements are attractive.
This thesis examines the design of such test circuits for one specific analog circuit,
the opamp. Test circuits to measure the gain, gain-bandwidth product, phase response and
the slew rate of the opamp have been designed and experimental results are presented. The
main advantages of these tests are that they are simple, fast, accurate and easy to
incorporate in an integrated circuit. / Graduation date: 1994

A PARAMETRIC STUDY AND REDESIGN OF THE BLAUSCHILD HIGH SPEED INSTRUMENTATION AMPLIFIER ARCHITECTUREGrantham, Clayton Bruce, 1955- January 1987 (has links)
This work contains the analysis and redesign of a translinear circuit. This circuit appeared in the article by Robert Blauschild. The Blauschild circuit was analyzed on H-SPICE, a VAX computer circuit analysis program, with Burr-Brown Integrated Circuit Process 30 models. Circuit improvement to input voltage to current converter stage and circuit simplification of the output stage were implemented and simulated in the redesign. The results of the two simulations were compared, which showed that the improvements were valid and useful. Going through this redesign cycle of circuit analysis, computer simulation and bread-boarding served as an actual design engineering application with a real problem, solution, and result scenarios.
