Exercise 3.4 Biasing a clap switch circuit

a)

b)

An answer:
Assuming the BJT satisfies $i_C=I_{C0}{e}^{\frac{q\cdot v_{\mathit{BE}}}{\mathit{kT}}}$ without any dependency on $V_{\mathit{CE}}$ : $$\begin{array}{rcll}& V_{C,T1}& =V_{\mathit{CC}}-I_{C,T1}R3& \\ & & I_{C,T1}=\mathit{\beta fe}{I}_{B,T1}& \\ & & I_{B,T1}=\frac{V_{\mathit{CC}}-V_{B,T1}}{R2}& \\ & V_{C,T1}& =V_{\mathit{CC}}-\mathit{\beta fe}\frac{V_{\mathit{CC}}-V_{B,T1}}{R2}R3& \end{array}$$

c)

An answer:
Substituting the numerical values for the various components shows that for all $\mathit{\beta fe}$ for the specified transistor type, the voltage drop across $R3$ would be larger than $V_{\mathit{CC}}$. This is in violation of the assumption on $V_{\mathit{CE}}$. In an actual circuit, this yields $V_{\mathit{CE}}\approx 0$ which does not correspond to proper biasing conditions.

d)

An answer:
0A (zero)
