Abstract

An all-MOS ASK demodulator with a wide bandwidth for lower industrial, scientific and medical (ISM) band applications is presented. The chip area is reduced without using any passive element. It is very compact to be integrated in a system-on-chip for wireless biomedical applications, particularly in biomedical implants. Because of low area cost and low power consumption, the proposed design is also easy to integrate in other mobile medical devices. The self-sampled loop with a MOS equivalent capacitor compensation mechanism enlarges the bandwidth, which is more than enough to be adopted in any application using lower ISM bands.
