Abstract

This paper presents a detailed study of on-chip spiral inductors with patterned ground shield (PGS) inserted between the spiral inductorand the silicon substrate. This new design has been implemented in source degeneration cascode lownoise amplifier (LNA) circuit to show how the PGS inductors improve the performance of the circuit. An operation in 1.8V supply voltage, source degeneration cascode LNA structure was studied with both technology and PGS inductors. In this paper, the Agilent ADS (Advanced Design System) simulation software and TSMC 0.18μm CMOS process parameters were adopted to achieve the low-cost characteristics and high integration to fit the performance of 2.4 GHz LNA design under IEEE 802.11a specification.According to the co-simulation results, the forward gain (S21) improved from 13.432 to 21.474 dB, and the (S12)is below the typical value of -15dB. The input impedance (S11) and the output impedance (S22) also represented good performance. In addition, the minimum noise figure was quite good. Thus, the LNA circuit with PGS inductorswas better in the availability and the possibility of 802.11a specification.
