Consider a general sense amplifier configuration shown in Figure 16.82 for a dynamic RAM. Assume that each bit line has a capacitance of 1 pF and is precharged to 4 V. The storage capacitance is 0.05 pF, the reference capacitance is 0.025 pF, and each is charged to 5 V for a logic 1 and to 0 V for a logic 0. The Ms and MR gate voltages are 5 V when each cell is addressed and the transistor threshold voltages are 0.5 V. Determine the bit line voltages v­1 and v2 after the cells are addressed for the case when (a) a logic 1 is stored and (b) a logic 0 is stored.
