Shown that the system in Fig. is a double integrator. In other words, prove that the transfer gain is given by $${{{V_0}\left( s \right)} \over {{V_i}\left( s \right)}} = {1 \over {{{\left( {CRs} \right)}^2}}},$$ assume ideal OP -AMP

A transistor having $$\alpha$$ = 0.99 and V_BE = 0.7 V, is used in the circuit of the figure.What is the value of the collector current?

A BJT is said to be operating in the saturation region if

An n-channel JFET has I_DSS = 1 mA and V_p = -5 V. Its maximum transconductance is ______
