This dual threshold action is called hysteresis, and implies that the Schmitt Trigger has some memory.
In order to find a solution for the conflicting read versus write operation design requirement in the 6T SRAM Cell, Schmitt Trigger principle is applied for the cross coupled inverter pair is shown the Figure 2.
The triangle wave signal has inverting polarity (consequence of inverting Schmitt trigger).

The analog buffer and the Schmitt trigger are supplied by the voltage values listed in Table 4.
The Schmitt trigger and the analog buffer have their own input capacitances noted [C.sub.i]; the capacitances [C.sub.ds1], [C.sub.ds2], and [C.sub.dg] are the MOSFET switches internal capacitances.
The output of the last amplifier is filtered and converted to a pulse using a Schmitt trigger. The design is extremely simple yet efficient since the measurement of the frequency requires only the number of signal transitions.
The Schmitt trigger and the electronically controlled switch implement a unit with an S--type current-voltage characteristic, typically observed in a transistor operating in an avalanche mode [1]-[6].
The IF section has an IF amplifier, limiting amplifier, FM demodulation circuitry and a Schmitt trigger. The IF signal from the mixer is filtered externally and amplified to provide the required drive level to the limiter.
Part 2 of the proposed schmitt trigger consists of a PMOS, (P3) and a NMOS, (N3) where both the MOSFET is directly connected through the gate terminal of each.
Figure 22 shows point 4 of the circuit, that is IC 8 with the output voltage of Vpp=10.2 V and the output signal is Schmitt triggered and changed the signal into square mode.
