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.
