SYSTEMS AND METHODS FOR ADJUSTING THE GAIN OF A RECEIVER THROUGH A GAIN TUNING NETWORK |
摘要 |
A circuit is described. The circuit includes a low noise amplifier (LNA), a passive switching core (PSC), a transimpedance amplifier filter (TIA-filter) and a degenerative-impedance gain-tuning network (Zdeg network) having a first Zdeg network input lead, a second Zdeg network input lead, a first Zdeg network output lead and a second Zdeg network output lead, wherein the first Zdeg network input lead is coupled to a first output lead of the LNA and the second Zdeg network input lead is coupled to a second output lead of the LNA, and wherein the first Zdeg network output lead is coupled to a first signal input lead of the PSC and the second Zdeg network output lead is coupled to a second signal input lead of the PSC. The LNA, the Zdeg network, the PSC, and the TIA-filter together form a receiver. A receiver gain is adjusted by the Zdeg network. |
