New Multiplier/Divider Using a Single Cdba

“…The workability of the proposed circuit, in its various application modes, has been verified by SPICE simulations employing the CMOS CDBA architecture of [2] using 0.35 µm CMOS technology and some sample application results have been presented. Using drain current equation of all the MOSFETs operating in triode region in terms of V gs and V ds , from (2), the voltage output of the circuit is found to be 1 A closer look at the circuit of Fig.3 of [14] reveals that the composite connection of the two CFOAs therein is exactly configured as a CDBA!…”

“…The Current differencing buffered amplifier (CDBA) [1] and its current-controlled version have received significant attention in literature as they have been shown to offer a lot of flexibility and versatility in analog circuit design, for instance, see [2,3,4,15,16,17,18] and the references cited therein. Several bipolar and CMOS implementations of the CDBA have also been advanced over the years such as those in [1,2,3,4] and [16][17][18][19][20][21][22].…”

New Squaring and Square-rooting Circuits Using Cdba

“…In order to maintain compatibility with existing voltage processing circuits as well as taking advantages [2] of the current-mode circuits, the new active element called Current differencing buffered amplifier (CDBA) [3] has received significant attention in literature since it can operate in both currentmode as well as voltage-mode. In earlier literature, the CDBA has been shown to offer a lot of flexibility in linear analog circuit design [3,4,5,6]. However, the use of CDBA in realizing non-linear functions has rather been limited [7,8,9].…”
