Because of higher performance requirements, infrastructure transceivers have historically employed lower levels of on-chip integration than their handset counterparts. One of the main limiting components preventing on-chip integration is the Local Os

In this paper, the DCXO is based on a Pierce oscillator with two MIM capacitor arrays for tuning the anti-resonant frequency of a 19.2MHz crystal. Each array of MIM capacitors is thermometer-coded and formatted in a matrix shape to facilitate layout.

Wireless audio applications at 5.8GHz require a wide band GFSK modulator with small distortion and very low power consumption. The traditional open loop modulation technique is susceptible to pulling. More advance close loop modulation requires preci

Integrating a power amplifier with the rest of a transceiver poses unique challenges particularly at 5.8GHz, where parasitic couplings are inevitable. In this paper we propose system and circuit techniques that are necessary in order to realize a RFI

The grating is divided to a cascade of unit cells. For each of the unit cells a transmission matrix is derived. For analyzing the step junctions in a unit cell physical optics approximation is used. Transmission matrix of the entire grating is genera
