Abstract
A Second-Order bandpass Gm-C filter with a 1 GHz center frequency is presented. The circuit features an independent control of the cutoff frequency and of the quality factor. The fully-differential integrators use a gain-enhancement technique, capable of increasing the basic transconductor open-loop DC gain to 52 dB. The filter has been fabricated in a digital 0.7 µm, GaAs MESFET process featuring 25 GHz ft transistors. It dissipates 40 mW from a single 1.9 V power supply.
