摘要： A multi-stage device (200-1) includes multiple stages such as a first stage (221-1) and a second stage (222-1). During operation, the first stage (221-1) receives an input signal and outputs an intermediate signal based on the input signal. The second stage (222-1) is coupled to the first stage to receive the intermediate signal and produce an output signal. According to one configuration, the second stage (222-1) includes a transistor (228) and a circuit path between the first stage (221-1) and the transistor (228). The transistor component (228) is controlled to derive the output signal from the intermediate signal inputted to the circuit path.
