This paper discusses design and tuning techniques for a narrow-bandwidth sixth-order Chebyshev bandpass continuous-time filter at very-high-frequencies. The direct simulation of a doubly terminated LC ladder filter formed by three capacitor-coupled grounded resonator sections employs capacitors and operational transconductance amplifiers for implementation in a standard digital 1.2 μm CMOS process. The automatic adjustment of both the center frequency and quality factor is based on the successive approximation tuning algorithm
