Design of the analog blocks used in a field programmable mixed array (FPMA) in 90-NM CMOS technology

Abstract

The miniaturization trend in electronic circuits enforces integrating analog and digital circuits in a System On a Chip (SOC) solution, reviving a renewed interest in Field Programmable Mixed Arrays (FPMA). This approach has an advantage of implementing both analog and digital circuits in one chip. In this thesis we present the analog building blocks used in the analog core of a Field Programmable Mixed Array (FPMA). The analog array contains CABs (Con gurable analog block) with both con gurable and xed analog blocks such as OTAs with tunable transconductances, wide common-mode range OPAMP, comparator, linear voltage to current converter, current to voltage converter and capacitors bank. Filter application such as low and bandpass Gm-C lters in a frequency range from 10Hz to 120MHz has been implemented using the designed components. The circuit blocks were designed and layouts of proposed analog blocks were implemented in TSMC 90-nm CMOS process single poly nine-metal with single 1.2 V power supply.
