A T-coil network can be implemented as a high order filter for bandwidth extension. This technique is incorporated into the design of the input matching and output peaking networks of a low-noise amplifier. The intrinsic capacitances within the transistors are exploited as a part of the wideband structure to extend the bandwidth. Using the proposed topology, a wideband low-noise amplifier with a bandwidth of 3–8 GHz, a maximum gain of 16.4 dB and noise figure of 2.9 dB (min) is achieved. The total power consumption of the wideband low-noise amplifier from the 1.8 V power supply is 3.9 mW. The prototype is fabricated in 0.18 µm CMOS technology.
