A generic multilevel multiplying D/A converter for pipelined ADCs
—State-of-art implementations of pipelined ADCs can only realize a multiplying DAC (MDAC) with (2n –1) levels. However, the number of levels needed to optimize the performance ...

Multichannel SVD-based image de-noising
: - In this paper, we propose a multichannel SVD-based image de-noising algorithm. The IntDCT is employed to decorrelate the image into sixteen subbands. The SVD is then applied to...

Controlling chaos in DC/DC converters using optimal resonant parametric perturbation
—The method of resonant parametric perturbation is a simple non-feedback chaos control method which is easy to implement in practice. In this paper, an optimal strategy is applie...

Boundary control of a bipolar square-wave generator using second-order switching surface
- This paper presents a boundary control of bipolar square-wave generator using a second-order switching surface. The switching surface is derived by estimating the state trajector...
