1. A method comprising:
providing an electronic circuit comprising part of one of a wireless transmitter circuit, a wireless receiver circuit and a wireless transceiver circuit for processing wireless signals; wherein
the electronic circuit comprises a reference voltage source where the reference voltage source comprises:
a current source; and
a plurality of transistors disposed along a ladder of N electrical nodes;
node 0 is coupled to ground;
a gate of an ith transistor of the plurality of transistors is connected to node i−1;
a source of the ith transistor of the plurality of transistors is connected to node i;
a drain of the ith transistor of the plurality of transistors is connected to node i+1; and
the current source is sources are disposed within the gap left within the current path between node 0 and node 1.
