Delta-Sigma modulator 84dB SNR, 250Hz BW

Macro Name          Delta-Sigma modulator 84dB SNR, 250Hz BW  
Width (for Hard IP only) 0.8mm  
Height (for Hard IP only) 0.86mm  
Power 3.6uW for the modulator  
Short Description*(max 128 characters)  This IP is an ultra-low power SD-modulator optimized for low bandwidth, ultra-low-power applications, including sensor readouts, healthcare solutions and IoT. It is a discrete-time second-order SD modulator with fully differential switched-capacitor circuits. The quantizer is a 5b SAR-ADC with passive adder. Chopper compensation is used to remove the first integrator non-idealities. The modulator requires only a single 32kHz reference clock and doesn’t rely on high-speed, high-power clocks. Reference designs for ADC driver, reference drivers and decimation filters are available.
