CMOS LNA design for system-on-chip receiver stages

Abstract

Narrowband single-ended inductive source degenerated low noise amplifiers (LNAs) for "system-on-chip" receiver stages have been designed, simulated and compared using the Mietec CMOS 0.7 /spl mu/m process and the Cadence/BSIM3v3 tool with active or L-biased DC-bias circuitries. Since there is an intention to use LNAs for GSM and S-band low earth orbit (LEO) space applications, the operating frequencies have been chosen as 900 MHz, 2025 MHz and 2210 MHz.
