摘要： An optical mouse utilizing a linear array of photodiodes is provided with circuitry to correlate during each self-timed cycle a new image with a stored image from the previous cycle with the new image offset relative to the stored image one pixel (photodiode signal) to the right, one pixel to the left, and also with no offset. All three correlations are done at the same time in separate correlators. Decision as to motion to the right, to the left or no motion is made on the basis of maximum correlation output. The new image is not stored in a second store array for use during the next cycle until any motion is detected, but it is stored in a first store array during the cycle when half the precharged photodiodes discharge below a predetermined level in response to incident light. A new cycle is initiated by precharging the photodiodes when any decision of motion or no motion is made.

摘要： A pMOS EEPROM cell includes a source, drain, channel, control gate and well contact. The device is a fully functional single element p-type floating gate MOSFET. A floating gate overlaps the well contact and completely surrounds the drain and source implants. The pMOS cell is written to by means of hot-electron injection, using an intrinsic feedback mechanism to write analog values. Hot electrons are generated in the channel by means of hole impact ionization at the transistor's drain. The pMOS cell is erased by Fowler-Nordheim tunneling. The tunneling voltage is applied only to the well to tunnel electrons from the floating gate. The well-source and well-drain junctions are protected from breakdown by means of guard rings.

摘要： A three-terminal silicon MOS transistor with a time-varying transfer function is provided which may operate both as a single transistor analog learning device and as a single transistor non-volatile analog memory. The time-varying transfer function is achieved by adding or removing electrons from the fully insulated floating gate of an N-type MOS floating gate transistor. The transistor has a control gate capacitively coupled to the floating gate; it is from the perspective of this control gate that the transfer function of the transistor is modified. Electrons are removed from the floating gate via Fowler-Nordheim tunneling. Electrons are added to the floating gate via hot-electron injection.

摘要： A proximity sensor system includes a touch-sensor pad with a sensor matrix array having a characteristic capacitance on horizontal and vertical conductors connected to sensor pads. The capacitance changes as a function of the proximity of an object or objects to the sensor matrix. The change in capacitance of each node in both the X and Y directions of the matrix due to the approach of an object is converted to a set of voltages in the X and Y directions. These voltages are processed by circuitry to develop electrical signals representative of the centroid of the profile of the object, i.e, its position in the X and Y dimensions. Noise reduction and background level setting techniques inherently available in the architecture are employed. A conductive paintbrush-type stylus is used to produce paint-like strokes on a display associated with the touch-sensor pad.

The complementary outputs of the CMOS single phase register of the present invention are the outputs of the second pair of cross-coupled CMOS inverters. The ground connections of the first pair of cross-coupled CMOS inverters is made through a transistor switch which turns on in response to the first logic level.

摘要： A CMOS analog integrated circuit comprising a plurality of nodes for simultaneously computing the largest of the signals at inputs of the nodes. There is a common line supplying current and producing a maximum voltage potential and a plurality of nodes connected to the common line. Each node comprises a follower transistor having a source operably connected to the common line for sourcing current and a gate being the input of the node and being connected to a current signal input source providing a current signal to the node to be compared to the current signals at respective ones of the other nodes. There is an inhibitor transistor having a gate connected to the common line and a drain operably connected to the gate of the follower transistor. The inhibitor transistor provides the voltage output of the node and inhibits the voltage output at all nodes connected to the common line which have a current signal which is smaller than the largest current signal connected to one of the nodes. A plurality of non-linear resistors may be disposed in the common line between respective ones of the nodes of limit current flow therebetween and thereby form subgroups having a single "winner" with each subgroup. A slope limiting transistor may be diode-connected in series with the inhibitor transistor to limit the slope of the voltage output from the inhibitor transistor.

摘要： An integrated circuit amplifier having a random input offset voltage is adaptable such that the input offset voltage may be cancelled out. An input node is a floating input node and is coupled to a source of input signal by a first capacitor. A second capacitor is connected between the output of the amplifier and the floating node. An ultraviolet window above the second capacitor allows the floating node to be charged, by the application of ultraviolet light, to a voltage which effectively cancels the input offset voltage.
