33 / 68 page  www.ti.com EEG Specific Features Figure 36. Dedicated Reference and Bias Electrode Reference : The reference electrode (REF_ELEC) input is used to drive the negative inputs of the channel through SRB1 pin on ADS1299 device. The reference electrode is connected to the negative inputs of all the channels. This leads to increased leakage current on the reference electrode since current of all the channels gets added. The EVM provides an option to buffer the reference electrode to reduce the leakage. The disadvantage of the buffered approach is the additional noise of the buffer amplifier. The table below shows the jumper settings for the two options. Table 9. Dedicated Reference Drive Options through REF_ELEC JP7 JP8 Un Buffered Don’t care 1-2 Buffered 1-2 2-3 Bias : There is an option to provide the bias to a fixed electrode either through BIAS_ELEC or through BIAS_DRV. BIAS_ELEC option needs an external amplifier U11 to buffer the mid supply. For the BIAS_DRV option the buffer is built inside the ADS1299 chip. The BIAS_DRV option also helps in improving common mode rejection by implementing a feedback loop. The details on selecting the inputs for bias drive are discussed in Section 5.5.3 and Section 7.1.3. 33 SLAU443 – May 2012 EEG Front-End Performance Demonstration Kit Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated |
