The first topic of the thesis reveals a mini-invasive low-power measurement system for bladder pressure measurement. Not only can the mode of measurement be selected, the input range and amplification of instrumentation amplifier (IA) is also adjustable. The proposed system can measure the pressure in a bladder in a continuous mode. It also can monitor the pressure in a long-term mode with an automatic sleeping mechanism for power saving. The signal generated by the pressure sensor is sensed by an IA, which is then fed into the following ADC (analog-to-digital converter). The input range of the IA must be adjustable to keep the required linearity. The pressure range of the proposed system is found out to be 5 Psi with the maximum resolution of 1 cm-H2O, which covers the range of all of the known unusual bladder syndromes.
The second topic is a self-disable sense technique for content addressable memory (CAM). The differential match-line sense circuit can be self-disabled to choke the charge current fed into the match line right after the comparison result is generated. Besides, the 13-T CAM cell provides the complete write, read, and comparison functions to refresh the data bit and verify its correctness before searching. The average energy consumption of the searching process is 1.872 fJ/bit/search according to thorough simulations.
