A fully integrated 35GHz linearly Frequency Modulated Continuous Wave (FMCW) single-chip radar transceiver is successfully implemented in 65nm standard CMOS process. The single-chip transceiver is configured in one transmitter and two receivers and includes a wideband process-oriented optimized QVCO, a mm-Wave power amplifier, low noise amplifiers, low noise passive mixers, IF amplifiers as well as...
A simple low-power current reference using dual-threshold MOS transistors is introduced. The area required for this reference is small and the sensitivity of the output current to the supply voltage is low. Simulation results show that an implementation of this current reference in a TSMC 0.18um CMOS process with a 1.8V power supply is constant to within ±1.25% over the temperature range of −10°C...
This paper proposes a CMOS structure as a highly linear on-chip temperature sensor. As long as all transistors are in saturation, the output of the structure is a VDD independent voltage source that linearly expresses CMOS threshold voltage, and hence is approximately linear in temperature. A new sizing strategy is introduced following a combined analytical and numerical optimization approach, which...
This work focuses on a new compact 6-transistor CMOS temperature sensor with improved flexibility for achieving target temperature linearity with small die area and low power consumption. The temperature information is provided in a differential output voltage that is based upon the linear dependence of threshold voltage on temperature. Implemented in a 0.18μm process, simulation results indicate...
