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. | |
