This work presents an integrated system-on-chip (SoC) that forms the core of a long-term, fully implantable, battery assisted, passive continuous glucose monitor. It integrates an amperometric glucose sensor interface, a near field communication (NFC) wireless front-end and a fully digital switched mode power management unit for supply regulation and on(More)
A well-known limitation of sigma delta modulators is the generation of limit cycle oscillations for DC and slow varying inputs. These limit cycles give rise to undesired tones at the output of the modulator which result in the deterioration of the signal to noise ratio (SNR). However, the use of high dither signal amplitude results in raising the inband(More)
This paper presents a system on chip for a fully implantable cochlear implant. It includes acoustic sensor frontend, 4-channel digital sound processing and auditory nerve stimulation circuitry. It also features a digital, switched mode, single inductor dual output power supply that generates two regulated voltages; 0.4 V used to supply on-chip digital(More)
