    Abstract: A frequency converting element includes a mixer and a charge pump. The mixer has first and second input nodes and an output node, and an input code of the charge pump is coupled to the output node of the mixer. The charge pump receives a mixer output signal at the input node of the charge pump, and outputs an amplified version of the mixer output signal.

    Abstract: A method and device for receiving a wireless signal is provided. The device includes a passive mixer having a first input node, a second input node, and at least one output node. An oscillator is coupled to the first input node of the mixer. The output of a buffer is coupled to the second input node of the mixer. An antenna is operatively coupled to the input node of the buffer. The buffer is configured to provide isolation from the mixer.

    Abstract: A baseband signal-conditioning architecture applicable to radio receivers uses switched-capacitor techniques to provide high-performance signal conditioning in low-voltage, deep-submicron processes (e.g., 65 nm and below). In the architecture, a first mixer is coupled to an antenna receiving the signal, and outputs a first mixer output signal based on the signal received by the antenna. A buffer coupled to an output of the first mixer outputs a buffer signal based on the first mixer output signal. A first charge pump is coupled to an output of the buffer, and produces a first charge pump output signal based on the buffer signal. In some examples, a second charge pump is coupled to the output of the first mixer and produces a second charge pump output signal based on the first mixer output signal, and the buffer input is coupled to an output of the second charge pump.
