Consider the BiCMOS folded cascode amplifier in Figure 13.20. As­ ume the circuit and MOS transistor parameters are the same as in Example 13.11. Assume BJT parameters of β = 120 and VA = 80 V. (a) Determine the small–signal voltage gain, (b) If the effective capacitance at the output node is 2 pF, determine the dominant–pole frequency and the gain–bandwidth product.
