Abstract: A transconductance circuit comprises 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. The gate node of the first transistor is coupled to a source node of the second transistor via the first feedback device. The 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. The source node of the second transistor is coupled to the reference voltage via the second source-degeneration device.
