As one of the key clinical imaging methods, the computed X-ray tomography can be further improved using new nanometer CMOS sensors. This will enhance the current technique's ability in terms of cancer detection size, position, and detection accuracy on the anatomical structures. The current paper reviewed designs of SOI-based CMOS sensors and their architectural design in mammography systems. Based on the existing experimental results, using the SOI technology can provide a low-noise (SNR around 87.8 db) and high-gain (30 v/v) CMOS imager. It is also expected that, together with the fast data acquisition designs, the new type of imagers may play important roles in the near-future high-dimensional images in additional to today's 2D imagers.

Instrumentation amplifiers (IA) play a crucial role wherever small differential voltages need to be amplified precisely in the occurrence of a any voltage at the input. It must therefore attribute high input-impedance, small input-referred noise and offset voltage, large differential-voltage gain without feedback and significantly cast-off deviations on power-supply and common mode voltages. In this paper efficient instrumentation amplifier with high gain, high CMRR and larger bandwidth is implemented. The proposed differential amplifier may be used for various control systems as well as small signal conditioning circuits; instrumentation amplifier having larger product of gain and bandwidth would encounter maximum application in these desires.

Portable wheel loads measure plate is force sensor based on strain measure and it can bear multidimensional force simultaneously. It is able to recognize radial wheel load through decoupling. Signal conditioning of the sensor will affect the measure accuracy. There are many strain-gauges in the plate. So the signal of measure plate will include CM noise, thermal noise and high shift. The signal conditioning aimed at these disadvantages should be high gain, high accuracy, low noise, low shift, high CMRR. Multisim is adopted to analyze the signal conditioning including strain measure amplifying circuit, instrumentation amplifier AD620, operational amplifier OP07. It is turned out to be low linear distortion and is able to satisfy practical application through the experiment.
