Answer / manoj
IC( Integrated Circuit) is made of Transistor inside. If
this transistor is PNP( P-Emitter N-Base P-Collector) type
then to make transistor in active region, Jc( Collector
junction) must be in Reverse bias condition for that Vcc
(DC power supply )must be negative.

Answer / mohan raj
in IC mostly we use transistor its act as differential
amplifer,negative feedback amplifier,instrument amplifier &
isolation amplifier such type of amplifer need dc -ve
voltage to create a inverting signal by transistor biasing
thats why -ve dc voltage need

Answer / vinay
ic requires transistors which requires both negative and
possitive power supply

Answer / maheboob
Because IC consist of many transistor, Operational
Amplifiers or differential amplifier etc. So to operate the
circuitory -ve power supply is required.
