If not properly initiated, even-stage ring oscillators may resonate in undesirable ways. When this occurs, their output frequency can be higher than expected and they can no longer be employed as VCOs in PLL designs. In this paper, we analyze this is

Electrical simulation gives a good evaluation of the performances of sigma-delta modulators but could require too long simulation times. In this paper we introduce the use of Verilog-A, which provides the capability to model the circuit topology of s
