• Linear current-to-time converter 

      Vlassis S., Souliotis G., Plessas F. (2019)
      In this work, a new current-to-time converter (CDC) based on current-starved inverter is proposed. The time delay of the output pulse edges is linearly proportional to a control current. The benefits of the proposed topology ...
    • Ultra Low-Voltage Current Squaring and Multiplier 

      Vlassis S., Souliotis G., Plessas F. (2019)
      This paper presents the designs of analog CMOS current squaring circuit and four-quadrant multiplier which are capable for operation under ultra-low supply voltage. The design approach is based on CMOS devices operated in ...
