Abstract
A multi-stage device includes multiple stages such as a first stage and a second stage. During operation, the first stage receives an input signal and outputs an intermediate signal based on the input signal. The second stage is coupled to the first stage to receive the intermediate signal and produce an output signal. According to one configuration, the second stage includes: i) a transistor, and ii) a circuit path between the first stage and the transistor. The transistor component is controlled to derive the output signal from the intermediate signal inputted to the circuit path.
Claims24
An amplifier comprising:
- a first stage to receive an input signal, the first stage producing an intermediate signal based on the input signal;
- and
- a second stage coupled to the first stage to receive the intermediate signal and produce an output signal, the second stage including:
- i) a transistor, and
- ii) a circuit path between the first stage and the transistor, the intermediate signal inputted to the circuit path to derive the output signal from the intermediate signal.
A method comprising:
- receiving an input signal at a first stage of a circuit;
- generating an intermediate signal from the input signal;
- inputting the intermediate signal to a circuit path coupled to a transistor in a second stage of the circuit;
- and
- deriving an output signal from the intermediate signal inputted to the circuit path.
