Three identical RC-Coupled transistor amplifiers are cascaded. If each of the amplifiers has a frequency response as shown in figure, the overall frequency response is as given as

Consider the following statements in connection with the CMOS inverter in the Figure. Where both the MOSFETS are of enhancement type and both have a threshold voltage of 2V.

Statement 1: T₁ conducts when V_i $$ \ge \,2\,V$$.
Statement 2: T₁ is always in saturation when $${V_0}\, = \,0\,V$$.

Which of the following is correct?

The circuit in the figure employs positive Feedback and is intended to generate sinusoidal oscillation. If at a frequency f$$_0$$, B(f)= $${{\Delta {V_f}(f)} \over {{V_0}(f)}} = {1 \over 6}\,\,\angle {0^0}$$ then to sustain oscillation at this frequency.
