These characteristics are similar to ideal amplifier characteristics and, hence, a cmos buffer or inverter can be used in an oscillator circuit in conjunction with other passive components. Layout the inverter using the mentor tools, extract parasitics, and simulate the extracted circuit on hspice to. Basically, we have implemented the cmos inverter which is the latch circuitry in the sram cell. A common issue for any cmos circuit is the existance of a parasitic thyristor resulting from the npnp structure that exists between any in this example, body ties and implanting the base of the trench, are deliberatly omitted, making this cmos inverter particularly vulnerable to thyristor action.
As usual, the pmos is connected to vdd cmos inverters are typically used to drive other mos devices by connecting a capacitor on the output end;
