      abstract     = {This brief presents a power-efficient approach for
                      generating control pulses for semiconductor spin qubits that
                      combines the flexibility of room-temperature electronics
                      with the scalability of cryogenic electronics. By
                      demultiplexing ramp pulses generated at room temperature,
                      capacitive loads are charged adiabatically, greatly reducing
                      power dissipation. The method is demonstrated using a
                      cryogenic circuit in a 22 nm CMOS technology, designed to
                      generate control pulses for shuttling semiconductor electron
                      spins. Post-layout simulations show that the circuit
                      achieves analog power dissipation more than two orders of
                      magnitude lower than the state of the art at frequencies up
                      to 1 MHz, more than one order of magnitude lower at 10 MHz,
                      and maintains superior efficiency up to several hundred MHz.
                      Furthermore, only two external AC inputs are required to
                      generate a wide range of pulse patterns with tunable
                      amplitudes across multiple outputs. These results
                      demonstrate the potential of the approach for large-scale
                      quantum processor architectures.},
