The expression is often abbreviated to simply oy, or elongated to oy vey ist mir (Oh, woe is me). The fuller lament may also be spelled as Oy vey iz mir. The main purpose or effect of elongating it is often dramatic, something like a cosmic ouch.he Latin equivalent is heu, vae! (pronounced, hoi, vai, amongst others); a more standard expression would be o, me miserum, or heu, me miserum. According to Chabad.org, an alternative theory for the origin of the Yiddish expression is that oy stems from Biblical Hebrew, and that vey is its Aramaic equivalent.
The final odd circuit within the op amp is shown in green. Here, the two resistors bias the transistor in what would seem to be an unusual way, since there is no apparent signal input to the base of the transistor. To understand its purpose, assume zero base current for a moment, and a V BE of 0.625 volt.he final odd circuit within the op amp is shown in green.

Op Amp Capacitive Differentiator Output â¢Again for inverting op amp circuits s f f out I = I V =â V â¢ Thus the output becomes dtdVV R I R C inout f in f s=â = â â¢ Where Ï = R f C s is the time constant of the RC circuit. â¢ Note the response time of op amp limits the operation â¢ Even if RC is very small.
