Methods to improve the operation of SOI devices

According to the present invention, a circuit and methods for enhancing the operation of SOI fabricated devices are disclosed. In a preferred embodiment of the present invention, a pulse discharge circuit is provided. Here, a circuit is designed to provide a pulse that will discharge the accumulated electrical charge on the body of the SOI devices in the memory subarray just prior to the first access cycle. As explained above, once the accumulated charge has been dissipated, the speed penalty for successive accesses to the memory subarray is eliminated or greatly reduced. With a proper control signal, timing and sizing, this can be a very effective method to solve the problem associated with the SOI loading effect. Alternatively, instead of connecting the bodies of all SOI devices in a memory circuit to ground, the bodies of the N-channel FET pull-down devices of the local word line drivers can be selectively connected to a reference ground. This would enable the circuit to retain most of the speed advantages associated with SOI devices while overcoming the loading problem described above. With this preferred embodiment of the present invention, the major delay caused by the bipolar loading effect is minimized while the speed advantage due to providing a lower, variable Vt effect is preserved. The overall body resistance of the individual devices has a minimal effect on the device body potential.

Vehicle body insulation resistance test method

The invention provides a method for testing the insulation resistance of a vehicle body, comprising the following steps: (1) generating a low-frequency AC signal and injecting the low-frequency AC signal into the vehicle body; (2) obtaining U through a first-level measurement circuit 9_30 ; 9‑30 The average value in one cycle reflects the unbalanced condition of the positive and negative poles to the body resistance; the variation dU in half a cycle 9_30 Participate in the calculation of the resistance value of the second-level measurement as the fluctuation parameter of the bus voltage; (3) obtain the AC voltage amplitude U through the second-level measurement circuit 9_25 , a single insulation resistance R = F (U 9_25 )*W, W is the weight, W=f(dU 9_30 ); (4) Take the average value of each measurement to obtain the vehicle body insulation resistance Ravr=(w1*R1+w2*R2+.....Wn*Rn)/(w1+w2+....Wn). On the basis of the original low-frequency signal injection method, the present invention correlates the weight of the weighted filter when calculating the insulation resistance with the variation of the DC bus voltage fluctuation, the weight is small when the bus voltage fluctuates greatly, and the weight is large when the bus voltage fluctuates small, thus Make the test results tend to be stable and reliable.
