    摘要: A charge pump arrangement for a phase-locked-loop has a current source circuit (60) which provides charging current to the phase locked loop, and a current sink circuit (90) which depletes charging current from the phase locked loop. The current source circuit (60) and the current sink circuit (90) have slew rates which have a predetermined relationship. In this way, the charge pump causes substantially no non-linear charge injection in the phase-locked-loop. Cascoded current mirrors (75, 85) are utilised to provide a high voltage with thin gate oxide technology. The arrangement has a relatively small die size. Since bias currents of the arrangement are mirrored according to the output current required, improved transient times are produced, leading to reduced phase noise.

    摘要: A bipolar memory array arranged in a row and column matrix is responsive to a plurality of word line driver transistors for selecting one row of memory cells thereof. The current flowing through each memory cell is provided by a pair or lateral PNP transistor current source loads. The collectors of the word line driver transistors are commonly connected for distributing the source of collector current flowing therethrough between the bases of all of the laterla PNP transistor current sources of the entire memory array which maintains a constant current flow through each of the memory cells during the select and deselect cycles thereby maintaining a constant memory cell array power dissipation which allows for expanded capacity of the memory array and a performance improvement.

    摘要: Improved semiconductor devices having minimum parasitic junction area are formed by using multiple buried polycrystalline conductor layers to make lateral contact to one or more pillar-shaped epitaxial single crystal device regions. The lateral poly contacts are isolated from each other and from the substrate and have at least one polycrystalline pillar extending to upper surface of the device to permit external connections to the lowest poly layer. The lateral epi-poly sidewall contacts are recessed under the intervening oxide layers to separate them from the active device regions in the center of the epi pillar.The structure is made by depositing three dielectric layers with two poly layers sandwiched in between. Holes are anisotropically etched to the lowest poly layer and the substrate. The exposed edges of the poly layers are oxidized. These edge oxide regions are removed in the holes where the device pillars are epitaxially grown. The remaining edge oxide regions isolate the buried conductor layers, contacts, and isolation walls. The polycrystalline pillar extending from the lowest poly layer to the device surface is formed at the same time as the epi-pillar. The structure is self-aligned and self-registering.

    摘要: A charge pump (102) and method of charge pumping a low voltage (V.sub.DD)) to generate a higher voltage (V.sub.PP). A primary pump (160, 179, 180) receives complementary clock signals (CLK1, CLK2) that control charging and transfer cycles of the charge pump. During the charging cycle, a capacitor (150) stores a charge developed from the low voltage. On the transfer cycle, the charge is transferred to an output (138, 177, 178) through a switching transistor (152) disposed in a well region (202) to develop the higher voltage. A secondary pump (162, 187, 188) charge pumps the output voltage to generate a more positive bias voltage for biasing the well region to disable a parasitic PNP transistor of the switching transistor.

    摘要: A circuit (28) and method of sensing data stored in a memory circuit provide a reference current (I.sub.REF) that tracks memory cell current (I.sub.BIT) over a range of temperatures and power supply voltages. A comparator circuit (66) senses the memory cell current with respect to the reference current to produce the stored data (V.sub.DATA) By sensing current rather than voltage, the voltage swing on a high capacitance bitline (39) can be reduced to improve speed. The reference current is set during testing of the circuit by applying programming voltages (V.sub.WELL, V.sub.CG, V.sub.BL) to a reference device (52) that matches a storage device (36) in the memory cell (30).

    摘要: A circuit and method modify data stored in a storage element (30) of a memory circuit (110) when high voltages used for such modification exceed transistor breakdowns. A charge pump (302) produces a pumped voltage (V.sub.P1) for modifying the data. A monitor circuit (304) produces an enable signal (V.sub.PEN) to activate other power supply voltages when the pumped voltage reaches a predetermined voltage level for allowing the data to be modified. A routing circuit (832) selects between the pumped voltage and a first voltage (V.sub.DD) in response to a first control signal (HVENABLEP) to produce a selected voltage. A switching circuit (802-808) passes the selected voltage to the storage element (30) to modify the data when the first supply voltage is selected by the routing circuit.

    摘要: An active load for a CML or ECL logic gate for substantially increasing the speed of the gate comprises a transistor having its base coupled to its collector by a first resistor, and its collector-emitter path coupled in series with a second resistor. This load provides an inductive impedance when the small signal emitter resistance is less than the sum of the resistance of the base and the first resistor, causing a peaking effect resulting in high switching speed.
