A 24-segment current-steering transmitter with 3-tap pre-emphasis and linear auto-tuned active line terminations is presented. A linearized resistor-MOSFET termination structure for continuous impedance tuning is proposed to maintain an accurate output voltage level (σ=1%) and good impedance matching (σ=2%). This enables larger signal drive strengths thanks to more efficient supply utilization. The...
This paper presents ways of enable and power-down functionality implementation in HV SoI buffers. Several HV buffer topologies are taken into account. Power-down, high input and output impedance functionality implementation approaches are presented and discussed.
A high intercept points, cost-effective, and power-efficient switching FET double balanced mixer (DBM) is reported. The Switching FET DBM demonstrated in this work offers input intercept points (IIP3) and conversion loss typically 44 dBm and 8.5 dB respectively with 15 dBm LO power for the frequency band (RF: 900-2150 MHz, LO: 850-1950 MHz, IF: 50-200 MHz). The measured interport isolation is typically...
