Abstract
An amplifier for wireless receivers and an associated method is provided. The amplifier provides an output signal to an output terminal in response to an input signal received from an input terminal, and further includes a first block and a second block. The first block is coupled between the input terminal and the output terminal, and includes a gain control terminal and a first transistor. The gain control terminal is coupled to a gain control signal, while the gain control signal is provided such that the first transistor is kept operating in a triode region, and a gain of the output signal over the input signal can be seamlessly tuned in response to the gain control signal.
