Description
Abstract:	A continuous-time monolithic filter is designed for the nominal specifications of [function][o] = 10 MHz and Q = 10. The filter topology exploits the transconductance amplifier based integrator as the basic building block to take advantage of its post-fabrication tuning ability as well as its better high frequency performance than the other blocks. A fully balanced input structure is employed to improve the input linear range, whereas the phase compensation is provided to tune out the excess phase related Q enhancement in the filter employing this integrator. To obtain the high operation frequency, intrinsic capacitances of the MOSFET are utilized as the load capacitance of the integrator. A second-order bandpass/lowpass filter is fabricated using μx CMOS double metal process. The test results demonstrate that both [function][o] and Q can be adjusted through a wide range and readily tuned to meet the desired specifications. Excluding on-chip output buffer, the filter requires the total chip area of 546 x 170 μm^2 and dissipates 69 mW to 72 mW of power.
