Answer / rajashekar @ nitt

give input at base and connect resistor at collector and
gnd at emitter,vcc at collector finaaly take output at
collector.

Answer / harshgandhi126

A single transistor itself is an inverter.Connect resistor
and +Vcc to collecot and Gnd to Emmiter. After that give an
input to Base terminal and take output between Collector
and Ground.

Answer / sharath & bhanu

Use a enhancement mode n-mos MOSFET and give i/p to base,
source to vdd and drain to o/p pin. Enhancement mode keeps
MOSFET always in ON state. Hence i/p logic '1' turns off
the transistor thus making o/p logic '0'

Answer / prateek

connect the gate of nmos to vdd so that it is always on
give the input at drain and tap the output from source.
