A high performance balanced photodiode sensor interface for the automotive industry is introduced. A novel switched current based architecture provides 100dB input current dynamic range. Correlated double sampling technique is used for 1/f noise suppression in the MOS input circuitry. Sigma delta ADC (13 bit) is used. The measured SNR is >66dB. Embedded… (More)
