Fig. 1. (a) Circuits of conventional CMOS bandgap voltage reference. (b) PSR small signal analysis model of conventional CMOS bandgap voltage reference. The base-emitter junction voltage of bipolar transistor, in generally the forward voltage of a pn-junction, exhibits negatives temperature-coefficient, which is about-1.5m VlaC [6], [7]. The difference(More)
To enhance the visual quality of an image that is degraded by uneven light, an effective method is to estimate the illumination component and compress it. Some previous methods have either defects of halo artifacts or contrast loss in the enhanced image due to incorrect estimation. In this paper, we discuss this problem and propose a novel method to(More)
In this paper, we propose a novelregularization term for super-resolution by combining a bilateral total variation (BTV) regularizer and a sparsity prior model on the image. The term is composed of the weighted least squares minimization and the bilateral filter proposed by Elad, but adding an ℓ1/2 regularizer. It is referred to as ℓ1/2-BTV. The proposed(More)
The main components of an artificial neuron are adders and multipliers. In order to implement neural network, large number of adders and multipliers are required. The efficient architectures for diminished-1 modulo 2<sup>n</sup>+1 multipliers are described. The results and operands of the new modulo 2<sup>n</sup>+1 multipliers use the diminished-1, avoiding(More)
