Abstract
This thesis presents the design, simulation and test results of a silicon germanium (SiGe) complementary metal-oxide-semiconductor (CMOS) linear regulator. The objective of the circuit is to power other analog devices regardless of the load current and input voltage changes. The application of this regulator is to be part of a project developing a miniaturized semiconductor platform that can be inserted into stems of crops in order to measure data inside the plant and then send it wirelessly to the user. The linear regulator was designed on a BiCMOS SiGe 0.13µm which is a GlobalFoundries process. It has been tested at room temperature and at 85 ºC with a supply voltage of 2.5 V and it holds an output of 1.2 V. The device demonstrates line regulation of 5 % and load regulation of 0.19 % as well as rejection of the power supply satisfying the specifications proposed.
