bandgap

   Also found in: Encyclopedia, Wikipedia 0.06 sec.
bandgap  (bndgp)
The difference in energy in a substance between electron orbitals in which the electrons are not free to move (the valence band) and orbitals in which they are relatively free and will carry a current (the conduction band). In semiconductors, some electrons are sustained in the conduction band by thermal energy. Energy released when an electron in the conduction band falls into a hole in the valence band is called bandgap radiation. See also holesemiconductor laser

In addition to the digital logic, these devices can incorporate high-voltage circuitry such as motor controller drives, DC/DC converters, and high-precision analog circuits including bandgap filters, ADCs and DACs.
The dots are small, so their bandgap is large and the gaps between rungs of the dots' internal energy ladders are big.
11 a/b/g transceivers, sigma-delta ADCs, automatic gain control circuits with bandgap and bias, high-speed I/Os, memory interfaces, and multi-GHz PLLs and DLLs.
