Abstract
The amplifier includes an input circuit configured to convert an input signal into a current; an output circuit comprising at least one switching element for reducing a voltage change of an output end of the input circuit and configured to provide an output signal; and a biasing circuit connected to the at least one switching element to form a feedback loop for reducing the voltage change of the output end of the input circuit.
Claims20
An amplifier comprising:
- an input circuit configured to convert an input signal into a current;
- an output circuit comprising at least one switching element and configured to provide an output signal;
- and
- a biasing circuit connected to the at least one switching element of the output circuit to form a feedback loop configured to adjust a voltage change of an output end of the input circuit.
A method of amplifying by an amplifier comprising:
- converting an input signal received by an input circuit into a current;
- outputting, by an output circuit including at least one switching element, an output signal;
- and
- adjusting a voltage change of an output end of the input circuit by a biasing circuit connected to the at least one switching element of the output circuit in a feedback loop.
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
- a first biasing circuit including a first amplifier having a first input terminal, a second input terminal and a first output terminal,
- wherein a gate 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 bias voltage to receive the first bias voltage as a first input and the second input terminal is connected to the first node 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.
