✦ Synopsis

Abstract

A novel on‐chip RF choke at 5 GHz is designed and measured for a class A operating Wireless LAN RF power amplifier (PA). The coplanar waveguide (CPW)‐based on‐chip RF choke is implemented as an alternative component to inductors provided by the 0.35‐μm SiGe BiCMOS technology. The CPW RF choke is designed at 5 GHz, and has a length of 1600 μm and loaded with a capacitance of 0.95 pF. The measured impedance of the RF choke at 5 GHz is around 104 Ω. © 2007 Wiley Periodicals, Inc.

## Abstract A two‐state single turn spiral inductor design is simulated in a 130 nm technology and another design is simulated and measured in a 45 nm technology. Measurements show an 80% inductance increase at 20 GHz in the 45 nm technology and a simulated 76% increase at 24 GHz in the 130 nm tech
