  Reference Circuit

  , US2006/0033557A1; US7242241B2

  A reference circuit comprising first and second field effect transistors connected to form a first current mirror, and a third and fourth field effect transistors connected to form a second current mirror, wherein a property of the first transistor is mismatched relative to the second transistor such that the threshold voltage of the first transistor is significantly higher than the threshold voltage of the second transistor, and the drain current versus gate-source voltage responses of the first and second transistors have substantially different gradients for current levels at which the reference current is operated.

  Adaptive ON-OFF spiking photoreceptor

  , Electronics Letters, Vol: 42, Pages: 196-198, ISSN: 0013-5194

  An adaptive spike generator circuit for intelligent vision chips is presented. A pulse frequency modulation spike encoder, capable of providing very high dynamic ranges with power consumption similar to an animal retina, has been developed. The circuit is inspired by the ON-OFF opponency algorithm used by the human eye.

  CMOS Current Mode Logic Circuits Using Subthreshold Conduction for Low Power Operation

  , GB2416255 (A)

  The switching transistors in a low-power CMOS current-mode logic circuit are biased to operate in weak inversion. The current-switching structure reduces noise and sensitivity to the process, voltage and temperature (PVT) variations which affect conventional subthreshold CMOS logic circuits. In retinal or cochlear implants analogue circuits operate in weak inversion to achieve low power, and by using current-mode logic satisfactory mixed analogue and digital low-power integrated circuits can be implemented. The logic swing is low and the data rate can be high. The current source Q1 operates in saturated weak inversion. The symmetry of the current-steering branches reduces input pattern sensitivity. A full adder is illustrated.
