Highly linear low noise transconductor

A system comprising:

• a transconductance circuit configured to convert an input voltage to an output current, the transconductance circuit comprising a first transistor, a second transistor, a first source-degeneration device, a second source-degeneration device, a first feedback device, and a second feedback device, wherein:
• a gate node of the first transistor is coupled to a source node of the second transistor via the first feedback device;
• a gate node of the second transistor is coupled to a source node of the second transistor via the second feedback device;
• the source node of the first transistor is coupled to a reference voltage via the first source-degeneration device;
• and
• the source node of the second transistor is coupled to the reference voltage via the second source-degeneration device.
