"overcomes chirp speed/ measurement accuracy trade-off... avoids complex digital predistortion, instead uses ramp tracker/ voltage-controlled oscillator calibration block... balances n-/p- channel metal-oxide-semiconductor varactors with opposing nonlinear characteristics to self-compensate for distortions. core circuit only 0.24 mm², mere 9.8 mW power, 1562.8 MHz/μs chirp rate at 1 GHz, 0.094% frequency modulation error... handles high-speed data and precise distance/ motion sensing simultaneously"
