This paper presents a modified current mirror topology derived from the well known two-VBE bipolar-only circuit structure used in RFIC power amplifiers. The novelty behind the proposed modified structure is that it uses a simple diode-based switching mechanism in order to maintain better bias current regulation, hence better RF gain regulation, as the reference voltage is lowered to values that are...
This paper presents a CMOS voltage regulator employing an operational-amplifier operated from a 1.8V supply with very low current consumption, capable of delivering a stable regulated 1.4V output voltage with high enough current sourcing capability for the biasing of GaAs HBT RFIC power amplifiers, and subjected to strong RF perturbations. These features are particularly important in multi-technology...
