A 1.5V resistive fuse for image smoothing and segmentation using bulk-
driven MOSFETs is presented. The circuit switches on only if the diffe
rential voltage applied across its input terminals is less than a set
voltage; it switches off if the differential voltage is higher than th
e set value. The useful operation range of the circuit is 0.4V with a
supply voltage of 1.5V and threshold voltages of V-Tn = 0.828V and V-T
p = -0.56V for n and g channel MOSFETs, respectively.
