The circuit shown in the figure uses matched transistors with a thermal voltage VT = 25 mV. The base currents of the transistors are negligible. The value of the resistance R in kΩ that is required to provide 1 μA bias current for the differential amplifier block shown is ___________. (Give the answer up to one decimal place.)
Enter numerical value using the virtual keypad. Round off where necessary.
