摘要： An integrated circuit having voltage isolation capabilities comprising a first galvanically isolated area of the integrated circuit containing a first group of functional circuitry for processing a data stream. The first group of functional circuitry located in a substrate of the integrated circuit. Capacitive isolation circuitry located in conductive layers of the integrated circuit provides a high voltage isolation link between the first group of functional circuitry and a second group of functional circuitry connected to the integrated circuit through the capacitive isolation circuitry. The capacitive isolation circuitry includes a differential transmitter for transmitting data in a differential signal to the second group of functional circuitry via the capacitive isolation circuitry. A differential receiver receives data within the differential signal from the second group of functional circuitry via the capacitive isolation circuitry. A detector circuit within the differential receiver detects the received data. The detector circuit monitors the differential signal and generates a first logical output when a voltage generated responsive to the differential signal exceeds a programmable voltage threshold level and generates a second logical output when the voltage generated responsive to the differential signal falls below the programmable voltage threshold level.

摘要： An integrated circuit having voltage isolation capabilities includes a plurality of communications channels for transceiving data from the integrated circuit. Each of the communications channel includes capacitive isolation circuitry located in conductive layers of the integrated circuit for providing a high voltage isolation link. The capacitive isolation circuitry distributes a first portion of a high voltage isolation signal across a first group of capacitors on a first link and a second link in the capacitive isolation circuitry and distributes a second portion of the high voltage isolation signal across a second group of capacitors in the first link and the second link in the capacitive isolation circuitry. A differential receiver on each of the plurality of communications channels receives the data on the first link and the second link. A differential transmitter on each of the plurality of communications channels transmits the data on the first link at a selected one of a first phase and a second phase and for transmitting the data on the second link at the selected one of the first phase and the second phase. The second phase is 180 degrees out of phase with the first phase. Each of the differential transmitters controls the selection of the first phase and the second phase on each of the first link and the second link such that only the first phase or the second phase is cross coupled onto a selected communications channel from adjacent communications channels.

摘要： A Schmitt trigger comprises first and second circuitry. The first circuitry receives an input voltage and provides an output voltage at either a logical “low” or a logical “high” voltage level responsive to the input voltage and a first bias voltage. The second circuitry connects to the first circuitry to generate a second bias current for generating the output voltage. The second bias current is larger than the first bias current. The Schmitt trigger operates in a low power mode of operation using only the first bias voltage to maintain the logical “low” voltage level or the logical “high” voltage level at a substantially constant level. In a high power mode of operation the Schmitt trigger uses the second bias voltage during transition periods between the logical “low” voltage level and the logical “high” voltage level.

摘要： A technique for reducing power dissipation and circuit area for a high voltage application includes creating a low-voltage, local power supply for use with local circuitry. In at least one embodiment of the invention, an apparatus includes an output node configured to provide a regulated output voltage. The apparatus includes a variable current source coupled to a first power supply node, wherein the variable current source is configured to provide an output current to the output node based on a control signal on a control node. The apparatus includes a feedback circuit configured to generate the control signal based on a mirrored current. The mirrored current is a mirrored version of a residual current flowing between the output node and a second power supply node. The regulated output voltage has a voltage level less than the voltage level on the first power supply node.

摘要： An input digital signal is converted to an analog signal using a main digital to analog converter (DAC) and a sub DAC. An offset value is subtracted from the input digital signal to generate an offset adjusted digital signal. The main DAC converts the offset adjusted digital signal to a first analog signal. A second digital signal is generated based on the offset value and a correction factor determined, at least in part, during calibration of the main DAC. The sub DAC converts the second digital to a second analog signal, which when combined with the first analog signal, provides an analog representation of the input digital signal.
