Abstract: Three circuit techniques for a 1.5 V, 512 Mb graphic DDR4 (GDDR4) SDRAM using a 90-nm DRAM process have been developed. First, a dual-clock system increases clocking accuracy and expands ...
Abstract: Physiological information provided by bio-potential signals is essential and pivotal for biomedical sensors. As the first stage in the signal chain of the sensor, impedance matching of the ...
