This paper presents an inductorless, 10Gbps automatic gain control (AGC) circuit including a speed enhanced variable gain amplifier (VGA), a power detector, a comparator and a switching exponential function generator for extended dB-linear performance. Third order interleaved feedback technique is utilized to enhance the speed of the current steering VGA stage. A stagger-tuned switching architecture for CMOS exponential function generation is utilized to achieve a dB-linear gain control range of 45dB with better than ±0.5 dB gain error. The AGC circuit achieves a maximum data rate of 10 Gbps for 2
