With the popularization of the Data-Over-Cable Service Interface Specifications (DOCSIS) product, many devices have been installed in client sides. the issue of how to maintain the quality while providing quick repair becomes more and more important. in some practical circumstances, the cable modem may lose the factory data which include the calibration table and the digital certificates. These data...
This work presents a new simple passive 3D stylus for capacitive touch panels that detects the x,y-directional position and z-directional strength using a peak calibration algorithm. The proposed algorithm can successfully detect the touch information while eliminating noise, ultimately leading smoother and faster tracking. Analysis results of an experiment on a touch panel demonstrate the effectiveness...
This paper presents an all-digital multiphase delay-locked loop (ADMDLL) for wide-locking range and micro-power applications. To enhance locking range of the ADMDLL, we proposed the self-estimated successive approximation register-controlled (SESAR) algorithm, which uses the frequency-estimation selector (FES) to avoid harmonic lock issue. In addition, the FES can reuse the delay line to reduce circuit...
A 2.4 GHz fully-integrated MISO transceiver consisting of two receivers and one transmitter is implemented in 0.18 mum CMOS technology. To alleviate the cost of external front-end components, the RF transmit/receive (T/R) switch and a power-efficient linear CMOS PA are fully integrated on-chip. It shows 3.5 dB low noise figures in the receivers respectively. Also, the transmitter delivers an average...
A fully integrated transmitter front end with on-chip power amplifier (PA) in 0.18 um CMOS technology is presented. The on-chip PA employs dynamic bias technique to reduce power consumption and enhance linearity. In the measurement, it reveals the output PldB of the PA is 26.5 dBm. Also, the transmitter delivers an average power of 17.3 dBm with EVM of -28.1 while drawing 225 mA of DC current (PA...
