High Frequency Operational Amplifier

Brief Description

A high frequency operational amplifier that exhibits precision gain at high frequencies and has record high bandwidth and linearity at a given operating power.

Background

Since conventional operational amplifiers (op-amps) are unstable at high gains at high frequencies and may require complementary technology for implementation, there is a need for an op-amp that surmounts both of these obstacles in order to increase performance and decrease production costs.

Description

Researchers at the University of California, Santa Barbara have developed a high frequency operational amplifier. It exhibits precision gain at high frequencies and has record high bandwidth and linearity at a given operating power. Because it doesn’t require complementary devices, production costs are decreased, and the op-amp tolerates a wide range of external input and output impedances. It is applicable in a wide range of both analog and digital electronics.

Advantages

• Precision gain at high frequencies

• Record high bandwidth at a given operating power

• Record high linearity at a given operating power

• Decreased production costs due to a design lacking the need for complementary technology

• High tolerances of external input and output impedances

Applications

• Operational Amplifiers

• Analog and Digital Electronics
