High-precision signals are essential for medical diagnostics. However, motion artifacts in these devices can cause significant ambient light variation during PPG recording. This paper presents an accurate PPG recording front end with enhanced ambient light rejection (ALR). Quantization noise in a second-order sigma-delta modulator (SDM), used for direct current conversion, is reduced by extended counting of the modulator's residue. The first integrator of the SDM and the residue analog-to-digital converter (ADC) are reused in ALR circuits. The correlated double sampling (CDS) technique is enhanced by applying a first-order approximation of ambient light. Gain error in the residue ADC is reduced by charge compensation. The PPG front-end, implemented in a 180 nm process, achieves a dynamic range (DR) of 153.4 dB within a bandwidth of 20 Hz. The system operates with a minimum 1.28% duty cycle. Measurements of heart rate and blood oxygen at the fingertip and wrist verify the functionality of the PPG front end.","PeriodicalId":94031,"journal":{"name":"IEEE transactions on biomedical circuits and systems","volume":"19 4","pages":"839-849"},"PeriodicalIF":4.9,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143545355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultrasound has been proposed to wirelessly power and control millimeter-sized deeply implantable DDSs, but initial demonstrations encountered challenges in power transfer and release control reliability in dynamic <italic>in vivo</i> environments. In this work, we present a closed-loop implantable DDS using ultrasound wireless power and communication in conjunction with an electrochemical drug release mechanism. The system consists of piezoelectric transducers for wireless power and data transmission, a drug delivery module containing drug-loaded electroresponsive nanoparticles, and a custom CMOS integrated circuit for closed-loop drug release using a programmable potentiostat capable of providing potentials up to <inline-formula><tex-math>$boldsymbol{pm}$</tex-math></inline-formula>1.5 V and sensing current up to <inline-formula><tex-math>$boldsymbol{pm}$</tex-math></inline-formula>100 <inline-formula><tex-math>$boldsymbol{mu}$</tex-math></inline-formula>A. The chip also improves power transfer robustness by enabling ultrasound power combining and rectifier voltage feedback which can be used to adapt the power transmitter and minimize misalignment. Closed-loop release control is tested <italic>in vitro</i> using the wirelessly powered DDS at 8 cm depth by adjusting the potentiostat stimulus voltage based on feedback of redox current into fluorescein-loaded nanoparticles, resulting in consistent 2 <inline-formula><tex-math>$boldsymbol{mu}$</tex-math></inline-formula>g release across different fluorescein loading concentrations and a 39<inline-formula><tex-math>$%$</tex-math></inline-formula> reduction in release amount variation.
