Abstract :
A generalization of the differential-difference amplifier with multiple differential inputs and linear weights is presented. This is a compact versatile analog circuit building block with many applications in analog signal processing. Experimental results of a test chip prototype in 0.5 μm CMOS technology are presented that verify the operation of the circuit. SPICE simulations show potential of the circuit to operate with gain-bandwidth products of approximately 0.35 GHz
