Abstract :
We present the design and test results for D-band CMOS transmitter (Tx) and receiver (Rx) for ultra-high speed and short distance data communications. The Tx/Rx employs modulation/de-modulation based on Amplitude-Shift Keying (ASK) to facilitate a non-coherent data link without power-hungry PLL, data converters, and complex DSP. The Tx consists of a wideband 131~140GHz VCO along with an On/Off key controlled power amplifier to achieve >90% ASK modulation; the Rx consists of a digital controlled LNA, an envelope detector (ED) and a programmable gain amplifier (PGA) to achieve >60dB dynamic range. Both Tx and Rx are implemented in 65nm CMOS and occupy an active area of 0.03mm2/0.12mm2. Test results validate linkage data rates up to 2.5Gbps at the carrier frequency of 140GHz with Tx/Rx power consumption of 115mW/120mW, respectively.
