Level crossing time interval circuit for micro-power analog VLSI auditory processing
A low-power circuit for level crossing interval measurements on continuous-time auditory signals, as obtained from the outputs of an analog cochlear filter bank, has been designed and fabricated. Experimental results from a fabricated array of 9 level crossing transducers demonstrate frequency-to-voltage conversion over a range covering the audio band. The power consumption is less than 20 /spl mu/W per cell from a 5 V supply, for the speech frequency range.
