This is one of the lab questions. For VCC=5V, ICSAT=5mA and the transistor manufacturers guaranteed βmin=100, find values for RC and RB that will ensure that the transistor just saturates when driven by VIN=+5V. Would it be safe to use this value in a mass-produced version of the circuit? I calculated Rc and Rb using Icsat=(Vcc-Vcesat)/Rc and Ibsat=(Vin-Vbesat)/Rb. I got Rc=960 Ω Rb=85 kΩ I'm not very sure about the second part of the question. For mass-produced versions of the circuit does βmin vary? Is it safe to use these resistor values?
