A PLAN:
IF V_s IS KNOWN V_0 CAN BE DETERMINED USING VOLTAGE DIVIDER.
TO FIND V_s WE HAVE A SINGLE NODE-PAIR CIRCUIT
ALGEBRAICALLY, THERE ARE TWO UNKNOWNS
AND JUST ONE EQUATION
THE EQUATION FOR THE CONTROLLING
VARIABLE PROVIDES THE ADDITIONAL EQUATION
SUBSTITUTION OF I_0 YIELDS
NOTICE THE CLEVER WAY OF WRITING mA TO
HAVE VOLTS IN ALL NUMERATORS AND THE
SAME UNITS IN DENOMINATOR
VOLTAGE DIVIDER
KCL TO THIS NODE. THE
DEPENDENT SOURCE IS JUST
ANOTHER SOURCE
