BJT Cascoded Active-load Differential Amplifier with CMFB
Build non-op-amp Common-Mode Feedback (CMFB) – This kind of high-gain differential input stage might be useful as part of an op-amp, but it’s a bit silly to include an op-amp within a stage another op-amp……
Some Examples
- 555 Timer as Oscillator / PWM Generator
- 7805 & Wall-wart Experiencing Voltage Drop-out
- Digital 4-bit counter and DAC
- Diode full-wave (bridge) rectifier
- Laplace transform step response and Bode plot
- LED with resistor biasing
- MOSFET switching inductive load
- Op-Amp inverting / non-inverting amplifier
- RLC resonance
- Zener diode voltage reference
Circuit simulation is an essential step in modern electronic design because it allows engineers to evaluate circuit performance under various operating conditions before hardware implementation. Testing parameters such as voltage, current, frequency response, and transient behavior improves design reliability while reducing the need for costly hardware revisions
