摘要： A signal processor comprises a reference voltage circuit (RVC) for imposing a reference voltage (VR) onto a capacitance (Cr). The reference voltage circuit (RVC) comprises a negative slope module (NSM) for providing a negative slope signal (SN), which has a magnitude that decreases when a voltage that is present on the capacitance (Cr) increases. A positive slope module (PSM) provides a positive slope signal (SP), which has a magnitude that increases when the voltage that is present on the capacitance (Cr) increases. A minimum selection module (MSM) controls a maximum current (IMX) that the reference voltage circuit (RVC) can apply to the capacitance (Cr) substantially in dependence on the negative slope signal (SN), if the magnitude of the negative slope signal (SN) is smaller than that of the positive slope signal (SP). The minimum selection module (MSM) controls the maximum current substantially in dependence on the positive slope signal (SP), if the magnitude of the positive slope signal (SP) is smaller than that of the negative slope signal (SN).

摘要： A composite transistor device is described which comprises a field effect transistor having its transconductance multiplied by the current gain of a current mirror amplifier. The transconductances of such devices can be matched with an accuracy approaching that with which simple field effect transistors can be matched. The higher transconductances of the composite devices make possible a variety of new circuits with distinct performance advantages.

摘要： In an amplifier, a first stage receives a differential input voltage, which is formed by first and second input voltages, and outputs a first differential current in response thereto on first and second lines having respective first and second line voltages. A second stage receives the first and second line voltages and outputs a second differential current in response thereto on third and fourth lines having respective third and fourth line voltages. A third stage receives the third and fourth line voltages and outputs an output voltage in response thereto. A slew boost circuit detects a slew condition, in which a threshold difference arises between the first and second input voltages, and outputs a slew current in response thereto for maintaining a slew rate of the output voltage during the slew condition. The first stage includes circuits for reducing a variable difference between the first and second line voltages.
