Stabilization Technique

We present in this paper a fully integrated low-noise high common-mode rejection ratio (CMRR) logarithmic programmable gain amplifier (LPGA) and chopped LPGA circuits for EEG acquisition systems. The proposed LPGA is based on a rail-to-rail true logarithmic amplifier (TLA) stage. The high CMRR achieved in this work is a result of cascading three amplification stages to construct the LPGA in addition to the lower common-mode gain of the proposed logarithmic amplification topology. In addition, the 1 / f noise and the inherent DC offset voltage of the input transistors are reduced using a chopper stabilization technique. The CMOS 180 nm standard technology is used to implement the circuits. Experimental results for the integrated LPGA show a CMRR of 140 dB, a differential gain of 37 dB, an input-referred noise of 0.754 μ Vrms, a 189 μ W power consumption from 1.8 V power supply and occupies an active area of 0.4 mm 2 .

The Impact

The total strain, elastic plus plastic, was measured with strain gages on valve bodies with internal pressure that caused surface yielding. The correlation of the simulated maximum principal strain was compared to strain gage data. A mesh sensitivity study shows that in regions of large plastic strain, mesh elements are required that are an order of magnitude smaller than what is used for linear elastic stress analysis for the same structure. A local mesh refinement was adequate to resolve the local high strain values. Both the location and magnitude of the maximum strain changed with a local mesh refinement. The local mesh refinement requirement was consistent over several structures that were tested. The test and simulation work will be presented along with the mesh sensitivity study. Some results on using an energy stabilization technique to aid convergence will be presented in terms of the impact on the predicted plastic strain.

Background: The hip is a structure of the human body in which occurs the junction of bone, articular, muscular and ligament structures. It is in the coxofemoral joint and has the function of supporting the whole-body weight, being one of the main joints responsible for ambulation. Objectives: To analyze the comparison of neural mobilization and rhythmic stabilization techniques in range of motion (ROM) and hip pain. Methods: The sample was composed by 20 patients, with mean age of 54±6 years, were divided into two groups of 10 patients: the patients who received the neural mobilization technique (G1) and the patients who received the rhythmic stabilization technique (G2). Results: The mean age of each group was 56±6 years (G1) and 52±6 years (G2). Among the evaluated, 12 (60%) were female, 14 (70%) were married, predominating the profession of housewife (35%). The great majority of the participants (95%) presented pain to the active movement, mainly to the movements of hip flexion and abduction. Regarding passive mobilization, 70% referred pains, predominating to the movements of hip external rotation and abduction. Conclusion: It was concluded that the neural mobilization and rhythmic stabilization techniques had satisfactory results in relation to ROM and pain in the hip region, but rhythmic stabilization had a greater gain of ROM and decrease of pain.
