摘 要：To reduce the power consumption of bio-sensors which will be potentially implanted into human body, compressed sensing is introduced by taking advantage of the sparsity of bio-signals. Using 32nm CMOS technology, the prototype is able to achieve 10-bit resolution under power consumption of 320 nW. The clock frequency is 20 kHz. The circuit described below is designed to compress bio-signal in time domain.
