Abstract :
To achieve wide-bandwidth performance, this paper proposes an on-chip high-speed limiting amplifier that employs a low-pass network topology. To avoid the parasitic effects of the on-chip spiral inductor, several short circuit coplanar stripline stubs fabricated with thicker top metal layer are used as passive inductors. The gain and bandwidth of the amplifier is studied employing a simplified MOSFET model, and simulated results are given for two different circuits structure. Finally, a test amplifier with a bandwidth of 6 GHz, gain of 15 dB and power dissipation of 70 mW is fabricated with the standard 1.8-V 0.18-μm digital CMOS process.
