What is the minimum input voltage to turn on the Transistor?
My aim is to find the minimum input voltage to turn on the transistor (T)
With the following assumption, voltage drop across the resistor R1 is very small,
Vin > 2.7V + 0.6V ( Zener voltage + drop across … V_BE)
That is, minimum input voltage should be minimum of 3.3V to turn on the transistor (T). …

How to calculate the output voltage of the mirror circuit?
voltage across R12
This drop across R12 will be equal to drop across R3 (10 Ω)
But when measures in Ltspice, Voltage across R3 = 12.56 mV
Voltage across R12 = 23.7 mV
As per my understanding voltage … Why voltage across R12 is 23.7 mV?
I suspect that D1 and R5 plays a role.
My intention is to calculate the output voltage Vout-A.
Could anyone suggest a method to find the output voltage Vout-A? …
