Design a common emitter amplifier circuit that operates optimally under given parameters: a 12V supply voltage and a target voltage gain of 300.
💡 Hint: Focus on balancing collector currents and selecting suitable transistor beta values.
Given two transistor amplifiers, one with an active load yielding a gain of 1500 and a bandwidth of 50kHz and another with a passive load having a gain of 200 and a bandwidth of 300kHz, compute the gain-bandwidth products and analyze their significance.
💡 Hint: Remember that the gain-bandwidth product often remains constant for amplifiers regardless of load type.
