To design and test a Common Emitter amplifier using BJT and plot its frequency response to determine bandwidth and gain-bandwidth product (GBW). The frequency response curve shows three regions: Low
| S.No | Component | Specification | Quantity | | :--- | :--- | :--- | :--- | | 1 | Transistor | BC107 / 2N2222 | 1 | | 2 | Resistors | 10kΩ, 3.9kΩ, 100Ω, 1kΩ | As per design | | 3 | Capacitors | 10µF, 100µF, 47µF | As per design | | 4 | Power Supply | 0-30V (Dual channel) | 1 | | 5 | CRO | 20MHz (Dual channel) | 1 | | 6 | Function Generator | 1Hz - 1MHz | 1 |
The CE amplifier provides high voltage gain (Av = -Rc/re) and medium input/output impedance. The frequency response curve shows three regions: Low frequency (affected by coupling/bypass caps), Mid frequency (constant gain), and High frequency (affected by transistor internal capacitances Cbc, Cbe). The bandwidth (BW) = fH - fL. Gain-Bandwidth Product = |Av(mid)| * BW.
