Abstract
A method, an apparatus, and a computer program product are provided. The apparatus provides a VCO signal. The apparatus is a VCO. The apparatus includes a first transconductance circuit. The apparatus further includes a second transconductance circuit coupled with the first transconductance circuit. The second transconductance circuit has a first configuration/mode (e.g., CMOS configuration/mode) and a second configuration/mode (e.g., NMOS configuration/mode or PMOS configuration/mode). The second transconductance circuit is configured to couple an input of the second transconductance circuit to the first transconductance circuit in the first configuration/mode. The second transconductance circuit is configured to isolate the input of the second transconductance circuit from the first transconductance circuit in the second configuration/mode. The second transconductance circuit may include a first transistor and a second transistor, and the input may be a gate of each of the first transistor and the second transistor.
