A RF amplifier gain calibration circuit uses a dummy amplifier to calibrate voltage gain and output voltage swing. The dummy amplifier's and a target RF amplifier share the bias circuit, thereby allowing accurate RF gain control against temperature, bias and process variations. A 0.18 /spl mu/m CMOS calibration circuit achieved gain control within +/-0.5 dB. The second circuit, an interleafed multi-stage filter and IF amplifier for use in a low-IF receiver, has an AGC circuit with a novel feedforward control that allows rapid convergence of the amplifier gain. When applied to a Bluetooth signal, convergence was achieved within 5 /spl mu/s even in the worst case blocking signal condition.","PeriodicalId":270304,"journal":{"name":"2003 Symposium on VLSI Circuits.

One analog voltage is selected from an analog bus to adjust the bias voltage of the detectors. We have fabricated 320/spl times/240-pixels sensor with 160 readout channels by using two 16-level analog buses. The variation in the bias current for this sensor decreased to 1/38 (5.2-bit), which helps to improve the sensor's temperature stability.

In this paper, a method called selective metal parallel shunting (SMPS) is proposed to move f/sub Qmax/ onto the desired frequency without additional processing steps. For a given planar inductor, a customized program is developed to find all the possible SMPS inductors and predict their Q/sub max/ and f/sub max/. Three sets of planar, all metal parallel shunting (AMPS), and SMPS inductors have been implemented in a 1P4M 0.35 /spl mu/m CMOS process to verify the proposed method. The prediction errors of Q/sub max/ and f/sub Qmax/ are less than 13% and 10%, respectively, between the simulated and measured ones. Moreover, three 2.3-2.4 GHz VCOs using planar, AMPS, and SMPS inductors, respectively, have also been realized. The phase noise of the VCO using SMPS inductors can be improved by 9.3 dB and 6 dB, respectively, compared to the VCOs using planar and AMPS inductors at 100 KHz offset frequency. The figure-of-merit (FOM) performance of the VCO using SMPS inductors can be comparable to the state-of-the-art publications.","PeriodicalId":270304,"journal":{"name":"2003 Symposium on VLSI Circuits.
