A Broadband Indirect-Feedback Power-to-Current LNA
2006 IEEE International Symposium on Circuits and Systems, 2006A dual-loop resistive-feedback power-to-current amplifier circuit to be implemented in SiGe or GaAs IC technology is presented. Simulation results indicate that any technology process with NFmin 20 GHz is able to achieve an overall noise figure less than 0.5 dB, an input return loss less than -15 dB and flat gain over a frequency range from 0.6 GHz ...

Indirect versus direct feedback in computer-based Prism Adaptation Therapy
Neuropsychological Rehabilitation, 2010Prism Adaptation Therapy (PAT) is an intervention method in the treatment of the attention disorder neglect (Frassinetti, Angeli, Meneghello, Avanzi, & Ladavas, 2002; Rossetti et al., 1998). The aim of this study was to investigate whether one session of PAT using a computer-attached touchscreen would produce similar after-effects to the conventional ...

Robust output feedback controller: indirect design
International Journal of Control, 1987In this sequel (see Chen 1987), two classes of controllers are constructed for uncertain dynamical systems using measured output via an indirect design approach.

Indirect adaptive state feedback control of linearly parametrized non‐linear systems
International Journal of Adaptive Control and Signal Processing, 1990AbstractTwo indirect adaptive linearizing controllers are proposed, in continuous time, for the class of non‐linear systems which are linearly parametrized and which can be linearized by state feedback through a parametrized diffeomorphism. In each case the stability of the closed loop is analysed in detail.

Analysis of an Unsupervised Indirect Feedback Network
1994Earlier work by the present author suggested the use of feedback structures to optimize information under conditions of noise at the output, or noise at both input and output (Plumbley, 1993a). Although these models were not designed as models of biological signal processing, the use of a feedback is highly suggestive for the role of the feedback ...

Noise model of indirect-feedback sigma-delta image sensors
2013 IEEE International Symposium on Circuits and Systems (ISCAS), 2013A novel architecture for a CMOS image sensor that incorporates a column-level sigma-delta (ΣΔ) analog-to-digital converter is presented. An indirect-feedback readout architecture where the digital output of the ΣΔ modulator is accumulated by a digital counter and converted to an analog voltage that serves as the reference voltage to which the buffered ...

ENHACING STUDENTS’ WRITING IN RECOUNT TEXT THROUGH INDIRECT FEEDBACK
Aisyah Journal of English Language Teaching (AIJELT), 2022This study aims to find differences in students' writing skills and aspects of writing that increase after applying indirect feedback as a technique. The method in this research is One group pretest-posttest. A total of 32 students from class X.10 were selected as the sample in this study. The data collection tool is a recount text writing test.

Indirect Adaptive Output Feedback for Large-Scale Systems
1993 American Control Conference, 1993This paper considers the design of an indirect adaptive output feedback controller for a class of interconnected systems. A recursive least-square parameter estimator is incorporated in the controller. Based on the LQ regulator design, a sufficient condition is derived for the existence of the local output feedback control law.

Direct and indirect output feedback design for TORA system
2014 American Control Conference, 2014This paper addresses the problem of stabilizing a TORA system without velocity measurement. For this purpose, two classes of output feedback designs, direct and indirect, are employed to design a nonlinear observer for estimating an unavailable variable (velocity variable).
