Keywords: | CMOS; Incremental analog-to-digital converter (IADC); low-area; low-power; sigma delta modulation | Issue Date: | Feb-2020 | Source: | Latin American Symposium on Circuits and Systems, LASCAS: 9068978 (2020-02) | Abstract (english): | This work presents an incremental 2nd-order sigma delta using a single operational transconductance amplifier. This design provides a good trade-off between time conversion, high bit resolution, power consumption and area utilization for a pressure sensing reading interface. The modulator, designed in 180 nm CMOS technology, has been optimized for low area utilization, occupying only 0.058 mm2. Post-layout simulations were performed showing a resolution of 150 μV while consuming 120 μW and 460 fJ/conv. The system has a resolution of 16 bits, a bandwidth of 2 kHz, an oversampling ratio of 512 and a sampling frequency of 2 MHz. |
