Abstract: A signal mixing circuit which mixes input signal(s) and oscillation signal(s) by mixer block(s) to provide a mixed signal. Each mixer block includes a summing node and a circuit unit; the summing node is arranged to provide a sum signal by summing an input signal and an oscillation signal, and the circuit unit is arranged to alternate between a first state and a second state in response to alternating of the oscillation signal; wherein the circuit unit is arranged to provide driving contribution to the mixed signal in response to the sum signal during the first state, and to stop providing driving contribution during the second state. An associated converter, e.g., a digital-to-analog converter, is also disclosed.

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.
