Sense amplifier threshold compensation |
摘要 |
A method and system are disclosed for adjusting the threshold in MOS devices, in particular for devices used in DRAM sense amplifiers. The effects of process and temperature variations on the threshold are compensated by a back-bias voltage. A comparison of an indicating voltage and a reference voltage is used to generate the back-bias voltage. The direction of back-bias voltage may be either in the backward, or in the forward bias direction.
