Abstract :
To achieve wide-bandwidth performance, an on-chip high-speed limiting amplifier is proposed employing a low-pass network topology. To avoid the parasitic effects of the on-chip spiral inductor, several short circuit coplanar strip line 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. 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.
