Abstract

Various aspects of integrated amplifiers, layouts for the integrated amplifiers, and packaged arrangements of the amplifiers are described. In one example, an amplifier includes an amplifier cell, and a biasing network coupled to the common gate transistor in the amplifier cell. The amplifier cell includes a common source transistor and a common gate transistor in a cascode arrangement, where at least one of the common source transistor and the common gate transistor comprises a field plate. Among other advantages, the amplifiers described herein can be biased with relatively high voltages and still operate like a single a common source transistor, without sacrificing reliability, performance, or requiring additional off-chip components, such as biasing networks of resistors and inductors.
