摘要： An integrated circuit chip includes a cascode amplifier having a first NMOS transistor with the gate receiving an input signal a source connected to ground through an inductance and a drain connected to the source of a second NMOS transistor. The drain of the second transistor is connected to a supply voltage through another inductance. The gate of the second transistor is connected to a DC bias voltage through a resistor and is connected to a first plate of an on-chip parallel plate capacitor. The other plate of the capacitor is connected to a wirebond pad for connection to a circuit board through a bond wire. The capacitor together with the inductance of the bond wire form a short circuit at the operating voltage of the amplifier.

摘要： A capacitor structure having a first level of electrically conductive parallel lines and at least a second level of electrically conductive parallel lines disposed over the lines in the first level, the lines of the first and second levels being arranged in vertical rows. A dielectric layer is disposed between the first and second levels of conductive lines. One or more vias connect the first and second level lines in each of the rows, thereby forming a parallel array of vertical capacitor plates. Electrically opposing nodes form the terminals of the capacitor. The parallel array of vertical capacitor plates are electrically connected to the nodes in an alternating manner so that the plates have alternating electrical polarities.

摘要： A Gilbert cell (Q3-Q8) of a mixer (11) controls a differential output voltage between a pair of output terminals (OUT1, OUT2) of the mixer (11). A polysilicon resistor (R7) of the mixer (11) applies a differential loading to the differential output voltage. A pair of current sources (Q11, Q12) of the mixer (11) provide biasing currents to the Gilbert cell (Q3-Q8). A pair of resistors (R8, R9) of the mixer (11) impede a flow of DC current through the current sources (Q11, Q12), respectively.

摘要： A power-on reset circuit input stage includes a current source charging a capacitor from a first power supply voltage to produce a reset signal, and a current shutoff means for shutting off the current source when the reset signal reaches a desired threshold voltage (i.e., when the capacitor is charged up). Beneficially, the current shutoff means comprises a transistor connected between the current source and a second power supply voltage. Advantageously, the transistor is controlled by a feedback voltage that may be the output signal, or a voltage derived from the output signal by a capacitive divider, for example.
