Wireless Health Care – The Doctor Will See You ALWAYS
Share an article from ieee spectrum: The Doctor Will See You ALWAYS “Wireless technologies are about to transform health care – and not a moment too soon.” By the way, it’s really a complicated feeling that I suddenly found … Continue reading

Low Current Measurement C: Feedback Ammeter
In the last post, shunt ammeter is briefly discussed. In this post, feedback ammeter will be introduced. 1. What are the basic components of a feedback ammeter? Fig.1 shows the general configuration of a feedback ammeter. The input current flows … Continue reading
Low Current Measurement B: Shunt Ammeter
There are two common methods of current measurement – the shunt ammeter and the feedback ammeter. In this post, the shunt ammeter method will be discussed. 1. What are the basic components of a shunt ammeter? Shunting the input of … Continue reading
Low Current Measurement A: Data Specification
There was a time when I devoted myself entirely to the IEEE state-of-arts. I was fascinated by their new architectures, new algorithms, and new building blocks. Later, when I sit whole days doing circuit layout. And then again, I sit … Continue reading
Pacemaker C: ADC Related
My design of an ultra-low power ultra-low speed ADC is for pacemakers. However, since I’m focusing on the design of stand-alone ADC, I somewhat neglect the exact requirement from the perspective of pacemaker system (I know it’s not good, but … Continue reading
Pacemaker B: A System View
I found a journal paper quite helpful, which is written by the engineers from St.Jude Medical. The paper was published in 2004, titled “A very low-power CMOS mixed-signal IC for implantable pacemaker applications.” Besides the paper, a book, titled “Bio-Medical … Continue reading
Pacemaker A: Some backgrounds
Since my current research focus is on ultra-low power ADC design for medical implant devices, among which the pacemaker is a well-known implantable medical device, so I came up with such a question – What kind of ADC is really … Continue reading
