3.75GHz Clock generator with bandwidth shifting algorithm
The power noise caused near to the PLL bandwidth considerably affects the PLL performance due to gain peaking. Therefore, it is strongly recommended to use an adaptive bandwidth PLL to switch bandwidth to lower the gain peaking under noisy environment. The proposed PLL checks whether the power noise frequency is near t..

2.7GHz 5000ppm Spread spectrum clock generator
This is a 2.7GHz 5000ppm Spread Spectrum Clock Generator (SSCG) which is designed for DisplayPort version 1.2. An Electro-Magnetic Interference (EMI) can be reduced effectively in high-speed interface communications. In this SSCG, fundamentally fractional-N PLL is implemented for this EMI reduction effect. A designed S..

Wake Up Receiver for 5.8GHz
This IP consists of envelope detector, amplifier, comparator, and delay-based BPF (Band Pass Filter). The RF input passes through RMS detector. If there is wake-up signal, the detector detects the envelope of the signal, and gives the detected signal to the following ASK demodulator block.
The envelope signal detect..
