WIDEBAND INDUCTOR-LESS BALUN-LNA WITH IMPROVED PICKUP NOISE REJECTION |
| 摘要 |
An inductor-less balun low-noise amplifier (LNA) includes a cross-coupled network coupled between first and second input terminals and first and second summing nodes. The cross-coupled network may include: a first non-inverting gain stage coupled between the first input terminal and the first summing node; a first inverting gain stage coupled between the first input terminal and the second summing node; a second non-inverting gain stage coupled between the second input terminal and the second summing node; and a second inverting gain stage coupled between the second input terminal and the first summing node. The cross coupled network may be configurable to provide common-mode rejection when operated in a differential or in a single-ended mode of operation. |

1. A device comprising:
a cross-coupled network coupled between first and second input terminals and first and second summing nodes; the cross-coupled network comprising:
a first non-inverting gain stage coupled between the first input terminal and the first summing node;a first inverting gain stage coupled between the first input terminal and the second summing node;a second non-inverting gain stage coupled between the second input terminal and the second summing node; anda second inverting gain stage coupled between the second input terminal and the first summing node,wherein the cross coupled network is configurable to provide common-mode rejection when operated in a differential or in a single-ended mode of operation. |
