“…Frequencies between 100 kHz to 15 MHz are commonly used for medical implants. Based on previous in vivo testing experience, a wireless power transfer frequency of 4 MHz is chosen [10]. At this frequency there was no evident degradation in the performance of other electronic equipments like CT scanner, heart rate monitor etc.…”

This paper describes the design, implementation and testing of a wireless blood pressure sensing implant. The implant is mounted on a stent graft. The implant along with the stent graft must fit into a 16F applicator stent delivery system. The implant is powered using the energy harvested from wireless power transmission. The measured pressure data is sent wirelessly to an external data reader hardware. The pressure measurement must have resolution of 1 mmHg.

“…This paper will describe the design of a system for measuring absolute pressure with a micro-machined capacitive pressure sensor. The design will be used in a blood pressure sensing wireless medical implant (Buhk et al, 2010) which will be permanently implanted inside an artery and powered through RF inductive wireless power transmission (Bradford et al, 2012).…”

A switched capacitor amplifier for measuring absolute pressure with a micro-machined capacitive pressure sensor using correlated double sampling has been designed in 130nm CMOS technology. The switched capacitor amplifier design uses a combination of correlated double sampling, input offset cancellation, and output offset cancellation to help reject 1 f noise and DC offset mismatch. A method for sizing the operational transconductance amplifier (OTA) components according to the system noise, accuracy, and bandwidth requirements is presented. 2. For the output swing, if V DD is the maximum output voltage level, V out pp = 2 V DD , and the

A Gain Boosted Folded Cascode using Telescopic Boosting Amplifiers with Switched Capacitor Input Level Shifters

This paper describes a single stage fully differential folded cascode operational transconductance amplifier (OTA) with fully differential gain boosting amplifiers designed in 1.2 VDC 130nm CMOS process technology. The amplifier is the driver for the analog to digital converter (ADC) of a blood pressure sensing medical implant [1] which uses wireless power transmission as its energy source [2]. The medical implant's design specifications require an amplifier with wide output swing, high accuracy, and the bandwidth to drive a differential 5 pF load at 4 ksps with minimum power consumption. The gain boosting amplifiers are telescopic cascoded amplifiers, which, by their design, have an input and output common mode voltage relationship which is opposite to what is needed for a gain boosted cascode configuration. To correct for this, a method for DC shifting the amplifier's input voltage using a switched capacitor network is presented.
