This paper describes an efficient structure of a pseudo-differential current starved delay element that is used in a four stages delay line targeted for analog/mixed Delay-Locked-Loops. The designed circuit has been simulated in ADS software, using TSMC 0.18 um CMOS process at 1.5V supply voltage. Body feed technique is used to widen applicable range of control voltage. The linearity of circuit is, also, improved compared to the conventional current starved delay elements. Moreover, improving… CONTINUE READING
