Patent ID: 11942907
Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. An amplifier comprising:
an input circuit configured to output a first signal based on an input signal;
an output circuit including a first switching element, a second switching element, a third switching element and a fourth switching element, and configured to provide an output signal; and
a first biasing circuit including a first amplifier having a first input terminal, a second input terminal and a first output terminal,
wherein the first switching element is a transistor;
wherein a gate terminal of the first switching element is connected to the first output terminal of the first amplifier of the first biasing circuit,
wherein the first signal is provided at a first node between the first switching element and the second switching element,
wherein the first input terminal of the first amplifier is connected to a first operating voltage of the amplifier to receive the first operating voltage as a first input and the second input terminal is connected to the first node at a source terminal of the first switching element to receive the first signal as a second input so as to form a first feedback loop configured to adjust a voltage change of the first signal of the input circuit, and
wherein the output circuit further comprises a capacitor configured to increase a bandwidth of the output signal.
