摘要： A linear voltage-to-current converter (LVCC) circuit includes two transistors, one P-channel and one N-channel. The input voltage is applied to the gates of both transistors. The drains of the two transistors are connected. The source of the p-type transistor is connected to a first voltage rail, and the source of the N-channel is connected to a second voltage rail of lower voltage. The output is the difference between the current through the P-channel transistor and the N-channel transistor. A linear current-to-voltage converter (LCVC) circuit is similar to the LVCC circuit, except that the gates of the transistors are tied to the drains of the transistors. The input current is supplied to the drains, and the output voltage is the voltage of the drains.

摘要： A power efficient high output swing operational ("HOOP") amplifier for integrated circuit analog signal processing is described. The operational amplifier includes a differential input stage and an output stage. The differential input stage is powered by a regular power supply while the output stage is powered by a voltage multiplier which results in a high voltage output swing without sinking significant power from the voltage multiplier. The high output voltage (e.g., 23 volts) is achieved using low voltage MOS devices. An output isolation technique is utilized to prevent possible latchup and contention. The operational amplifier also features a bias boot scheme to achieve a faster settling time from power up. In addition, the present invention provides realization of frequency compensation with highest possible breakdown and reduced noise coupling. A bias arrangement between input and output stages of the operational amplifier is used to further help reduce the power drawn from the voltage multiplier and decrease the settling time.
