Abstract
- A 1.8 mW wideband common-gate (CG) low-noise amplifier (LNA) with double capacitor-cross-coupled (CCC) feedback is presented for multiband wireless communication standards. To achieve a low-noise figure (NF) and high-voltage gain under low power consumption, the CG LNA is based on the double CCC feedback and current-reuse techniques. Post-layout simulated results for 0.18 μm CMOS implementations show that the voltage gain is 18.1 dB with a 3 dB bandwidth from 100 MHz to 1.7 GHz and the IIP3 is -4.9 dBm at 1 GHz. The average NF is 2.4 dB within the entire 3 dB bandwidth. The LNA consumes 1.8 mW from a 1.8 V DC supply and the active size is 0.15 × 0.14 mm 2 .
