ABSTRACT:
An integrated circuit includes a differential amplifier. The differential amplifier includes at least one output end. A circuit is coupled with the at least one output end of the differential amplifier. The circuit does not include a resistor-capacitor (RC) network and is configured for providing a negative impedance to the differential amplifier for adjusting a direct current (DC) gain of the integrated circuit.
