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.
