摘要： A biomedical sensor (20) is formed on a semiconductor substrate (22). Insulated dielectric layers (23, 24) are formed on the face and backside of the semiconductor substrate (22). Metal leads (26, 28) contact the substrate (22) through openings in the dielectric layer (23). The leads (26, 28) are also each connected to a set of interleaved longitudinal contact fingers (27, 29). A pair of contacts (30, 32) are formed on the opposite side of the substrate (22) from the contact figures (27, 29). A conductive biologic sample is placed over the interleaf fingers (27, 29), electrical measurements can be made through backside contacts (30, 32) so resistance measurements can be taken.

摘要： A dual-slope A/D converter circuit has an oscillator (14) whose timing frequency is determined by the value of an oscillator resistor (70) and a oscillator capacitor (72). An integrator (66) integrates an input voltage at a rate determined by an integrating resistor (64) and an integrating capacitor (68). The oscillator resistor (70) and integrator resistor (64) are designed such that their ratio will remain constant despite variations in actual value due to manufacturing inaccuracies. The oscillator capacitor (72) and integrating capacitor (68) are similarly designed. Consequently, an optimum peak integration value can be obtained at full scale input despite variations in actual resistive and capacitive values.

摘要： A touch screen system includes a capacitive touch screen (1) including a plurality of row conductors (7-1,2 . . . n) and a column conductor (5-1). A plurality of cotemporaneous orthogonal excitation signals (S1(t), S2(t) . . . Sn(t)) are simultaneously driven onto the row conductors, respectively. The capacitively coupled signals on the column conductor may be influenced by a touch (10) on the capacitive touch screen. Receiver circuitry (50) includes a sense amplifier (21-1) coupled to generate an amplifier output signal (r1(t)) in response to signals capacitively coupled onto the column conductor. WHT-based circuitry (35) determines amounts of signal contribution capacitively coupled by each of the excitation signals, respectively, to the amplifier output signal.

摘要： In a method and circuitry for sense amplification, a differential input voltage (84a-b) is input, and a differential output voltage (90a-b) is output. The differential output voltage (90a-b) is substantially minimized during a reset signal on a reset signal line (88). During the reset signal, the differential output voltage (90a-b) is biased in response to the differential input voltage (84a-b). After the reset signal, the differential output voltage (90a-b) is amplified in response to the biasing.

摘要： An amplifier includes an input circuit for alternately selecting input signals to be compared and a first bias circuit for producing self-bias when one of the input signals is selected. A second bias circuit stores the self-bias for use in the amplifier when the other of the input signals is selected for rejecting noise which may accompany power supply voltage applied to the amplifier.
