In this paper, a new self-tuning digital technique is reported for analog filters over VHF (very high frequency) applications, based on phase detector. By using a 0.35 mum mixed signal CMOS process, changes in frequency response of a 3rd-order low pass filter can be tuned with a 3% error over the designed value. This technique confirms the feasibility of the proposed scheme in analog filter applications...
By manipulating digital tools to include a single analog cell, the complete DAC and IF transmit path of a radio is automatically placed and routed in 0.12 mm2. Implemented in 0.18 mum CMOS, an over-sampled SigmaDelta modulator quantizes the data stream and a semi-analog filter selects a replica of the desired signal at IF. Based on instances of a 5-transistor analog cell, an integrated mixed-signal...
In this paper, a new auto-tuning digital technique is reported for continuous-time filters over VHF (very high frequency) applications, based on phase detector. By using a 0.35 mum mixed signal CMOS process, changes in frequency response of a 3rd-order low pass filter can be tuned with a 3% error over the designed value. This technique confirms the feasibility of the proposed scheme in continuous-time...
