Claim:
1. A gain-boosted n-path passive-mixer-first receiver, comprising: a number n of switch-capacitor (sc) sets connected in parallel, wherein the sc sets have a first node and a second node; a resistor, connected to the first node; and a transconductance amplifier, connected to the resistor and the second node; wherein each of the sc sets further comprises a third nodes at a connection point between the switch and the capacitor; wherein a high frequency voltage signal is input to an input of the transconductance amplifier, and a result low-frequency voltage signal is output at one of the third nodes; wherein the sc sets driven by a set of multiple-phase non-overlapping clock, with its clock frequency also defines the operating frequency of the receiver; wherein the low-frequency voltage signals at the third nodes have different phase with respect to each other.
