摘要： An improved charge transfer stage with an expanded output voltage range and high charge transfer efficiency is described. The charge transfer stage can be implemented as an output stage in a four phase clock negative charge pump system. The charge transfer stage comprises a PMOS pass transistor coupling the transfer stage input and output, a resistor between the transfer stage input and the pass transistor gate, a clock terminal, a capacitor configured PMOS transistor coupling the clock terminal to the gate of the pass transistor, and a diode from the transfer stage output to ground. When the transfer stage input goes low, charge is coupled through the resistor to pre-charge the gate of the pass transistor. The resistor has a higher junction breakdown voltage than a transistor which allows the gate of the pass transistor to be driven to a larger voltage. To provide sufficient charge to turn on the pass transistor, a logic high level greater than the power supply, such as 2 VCC, can be used for the clock signal coupled through the capacitor configured transistor to the gate of the pass transistor. To prevent the 2 VCC logic high level from forward biasing the p-n junction formed by the source and drain of the PMOS capacitor configured transistor with the well, the source, drain and well are coupled together. The charge transfer stage also includes a p-n junction diode coupled from the output of the stage to ground.

摘要： In a level shifter, first and second integrated-circuit resistors are connected in series between a source voltage supplying terminal and the ground. The first and the second integrated-circuit have a common temperature characteristic and a common line width. A third integrated-circuit is connected to the first integrated-circuit resistor in parallel and-has another temperature characteristic. The first, the second, and the third integrated-circuit resistors form a voltage divider which divides a source voltage Vcc into a divided voltage. A differential amplifier has a noninverting terminal which is connected to a connection point between the first and the second integrated-circuit resistors, an output terminal, and a inverting terminal which is connected to the output terminal. The differential amplifier supplies the divided voltage to an integrated circuit as a level shifted voltage.

摘要： A JFET pair having unequal pinchoff voltages is operated in saturation with equal source-drain current to channel width-to-length ratios to provide a reference voltage output. Positive or negative voltage references can be implemented using either n-channel or p-channel JFETs. The pinchoff voltage difference results from the channel for one JFET having a heavier doping level than that of the other JFET.

摘要： The present invention describes a bias generator (10) which supplies a temperature stabilizing bias current (72) to a main circuit (90). The bias generator (10) comprises a measurement unit (20) having a similar structure and temperature characteristic as the main circuit (90). Measurement unit (20) supplies a temperature dependent measurement signal (27). A temperature invariant element (40) supplies a temperature independent reference signal (47). These signals (27, 47) are compared in a differential amplifier (30) which controls variable current sources (50, 60, 70). The variable current sources (50, 60) supply the measurement unit (20), the temperature invariant element (40) and the bias current (72) for the main circuit (90) itself. A negative feedback is produced which results in a stabilized transconductance of the main circuit (90). Therefore, the bias current (72) which determines all other currents and the speed of the main circuit (90) is automatically adjusted to the needs. Power consumption can be reduced and the reliability of the main circuit (90) can be improved.
