  • Pulse modulated neural integrator circuit
    Patent number: 8504503
    Abstract: A pulse modulated neural integrator circuit is comprised of discrete analog electronic components and has a plurality of discrete stable states. In some embodiments, the pulse modulated neural integrator circuit is fabricated in whole or in part on an integrated circuit substrate using analog VLSI techniques. A phase locked loop circuit can use the pulse modulated neural integrator circuit in place of some conventional phase locked loop circuits.

  • Method and apparatus for current-mode ADC
    Patent number: 7714762
    Abstract: A current-mode analog-to-digital (IADC) has subnA sensitivity. An IADC cell receives an input current signal and provides an output to a comparator for comparison with an adjustable input reference signal. A digital output signal is generated and an analog output is provided to the next cell.
