    摘要: Linear integrated circuit capacitors having greater capacitance per unit area by using lateral flux. One embodiment comprises a two metal layer capacitor wherein each metal layer is comprised of two capacitor conductive components. The capacitor conductive components are cross-coupled so that the total capacitance is the sum of the vertical flux between the metal layers, and the lateral flux along the edges between the two capacitor conductive components in each of the metal layers. The lateral flux between the capacitor conductive components in a single metal layer increases the capacitance per unit area and decreases the bottom-plate parasitic capacitance. Increasing the length of the common edge formed by capacitor conductive components in a metal layer increases the capacitance per unit area. In one lateral flux capacitor, each metal layer is comprised of a plurality of rows, alternate rows are coupled together such that lateral flux is generated between each of the rows. The rows are also cross-coupled with rows in adjacent metal layers to provide vertical flux. Fractal shapes can be used to maximize the length of the perimeter of adjacent capacitor conductive components in a single metal layer. The Koch Islands and Minkowski Sausage families of fractals are particularly well suited for generating capacitor conductive component perimeter shapes. These fractals are generated by selecting an initiator shape and repeatedly applying a generator. The fractal shapes are generated by a computer program based upon user input parameters.

    摘要: A distributed electrostatic discharge (ESD) protection circuit for high frequency integrated circuits. A transmission line from an integrated circuit (IC) pad or package pin couples a plurality of ESD elements. The ESD elements, such as diodes, are distributed along the transmission line and coupled from the transmission line to ground or a power supply. The effective impedance of the transmission line and ESD elements is defined to match the impedance of an external line. Distributed ESD protection circuits provide a high frequency signal path that can be used well into the GHz frequency range and also provide effective ESD protection.

    摘要: A temperature sensor includes a bandgap reference circuit for providing a temperature-independent reference voltage, a biasing circuit that mirrors a current in the bandgap reference circuit for providing a temperature-dependent biasing voltage, and an amplifier responsive to the reference voltage and the biasing voltage for providing a temperature-dependent output voltage. Preferably, the temperature sensor is integral with a microprocessor and implemented in CMOS technology. The temperature sensor can be used, for instance, to reduce the clock speed of the microprocessor when the microprocessor temperature exceeds a predetermined temperature, or to store temperature-indicating data in non-volatile memory of the microprocessor to provide a thermal history of the microprocessor.

    摘要: A high gain, low voltage differential amplifier exhibiting extremely low common mode sensitivities includes a load element exhibiting a high differential resistance, but a low common mode resistance. The load element contains a positive differential load resistance and a negative differential load resistance, which offsets the positive differential load resistance. The output common mode level of the differential amplifier is one p-channel source to gate voltage drop below the power supply voltage prohibiting the common mode output voltage from drifting far from an active level. The differential amplifier also has application for use in a differential charge pump circuit. The high differential impedance of the differential amplifier allows the attainment of extremely small leakage, while a low common-mode impedance results in simplified biasing.
