In this work, a high resolution analog-to-digital converter (ADC) for use in harsh environments is presented. The ADC is implemented in bulk CMOS technology and is intended for space exploration, mining and automotive applications with a range of temperature variation in excess of 250°C. A continuous time (CT) sigma delta modulator employing a cascade of integrators with feed forward (CIFF) architecture in a single feedback loop topology is used for implementing the ADC. In order to enable operation in the intended application environments, an RC time constant tuning engine is proposed. The tuning engine is used to maintain linearity of …
