Abstract: A mixer for providing a mixed signal by mixing an input signal and an oscillation signal, comprising a follower and a switch. The follower is arranged to conduct a driving contribution from a bias terminal to an output terminal following a signal at an input terminal, wherein the input terminal and the bias terminal are respectively coupled to the input signal and the oscillation signal, and the output terminal is arranged to output the mixed signal. The switch is arranged to selectively conduct the output terminal to a reference level in response to alternating of the oscillation signal. An associated signal circuit is also disclosed.
