Abstract :
With the reduction of supply voltage motivated bypower reduction, the signal to noise ratio of digital signals has reduced. Alternately, signal can be represented as current while the supply voltage still remaining small. This gives rise to the field of current mode signal processing circuits. In this work, we propose a current mode analog Walsh-Hadamard processor while the control mechanism remains digital. The design is implemented in 0.35μm CMOS technology. Walsh-Hadamard transform is a complete transform and finds significant applications in the field of image processing, filter design, multiplexing. To the best of our knowledge, no such implementation exists in the published literature.
