“…A three stage SERO with load capacitances is simulated in 90 nm technology using Cadence Virtuoso platform. The supply voltage is varied between 0.3 V and 2 V. The value of the load capacitance is calculated using the equation in [12]. The circuit is first simulated with Rw = 2 and the new equation is compared with the conventional equations.…”

In this study, a new general expression for the frequency of a SERO is constructed, which includes two additional variables, Kd and Rw, and improves upon the traditional equations by accounting for all analysis models and various width ratios. When compared with the the conventional equations, the proposed equation is a better alternate to study the frequency response when the width ratio is concerned parameter for researchers which is addressed by the variable Rw. A three stage SERO is simulated in 90 nm technology using Cadence Virtuoso platform to establish this equation. The value of Kd obtained remains almost equal which justifies the reason for using this approach traditionally to calculate the delay.

“…In a similar method as before, the integral limits are now from 0 to VDD and VDD to 0 for equations (3) and (4), respectively. The propagation delays then obtained are given by (11) and (12) which leads to the frequency equation given by (13). This is the most common equation in literature.…”
