Abstract
This thesis is an exploration into the design of configurable analog block (CAB) for field programmable analog arrays (FPAAs) designed in modern complementary metal-oxide-semiconductor (CMOS) technologies. Specifically, this thesis develops a single configurable analog block (CAB) using an operational transconductance amplifier (OTA). A fully differential OTA is selected for its flexibility and the reliability of differential signals with respect to noise when compared to single-ended signals. The OTA is combined with a set of switches, controlled by a serial shift register, to allow for reconfiguration of the internal wiring, and two capacitor arrays used to fine-tune the frequency response of the circuit. Simulation results are provided for an OTA, the OTA operating in situ, and a band-pass filter, thus demonstrating the use of the CAB. A single CAB is constructed on a 0.13 µm CMOS chip.
