This letter presents an inductor-loaded 2:1 regenerative frequency divider operating up to 331.2 GHz in an InP HBT process, which, to the best of authors’ knowledge, is the fastest frequency divider reported thus far. On-wafer measurement shows that the divider is operating from 304.8 GHz to 331.2 GHz, with output power from 27 dBm to 12.3 dBm (no probe loss correction), while dissipating 85.5 ...

This work describes the design of a double-precision radix-8 divider. Low-power techniques are applied in the design of the unit, and energy-delay tradeoffs considered. The energy dissipation in the divider can be reduced by up to 70% with respect to a standard implementation not optimized for energy, without penalizing the latency. The radix-8 divider is compared with one obtained by overlappi...

The implementation of a programmable high speed divider for a CMOS Frequency Synthesizer, using 0.35 μm CMOS technology, is described. The Frequency Synthesizer is part of a RF transceiver to work in the 2.4 GHz ISM (Industrial, Scientific and Medicine) band. The programmable divider employs: a divide-by-32/33 dual-modulus prescaler composed by a divide-by-4/5 synchronous counter, using the Ext...

A broad-band power divider is presented in CMOS technology. The devices are realized by postprocessing chips that are fabricated in a standard 1.2m CMOS process. Developed postprocessing includes wire bonding for ground equalization, deposition of a stress-compensation layer, and selective etching of the silicon substrate. By employing coupled coplanar transmission lines, the area of dividers i...

In this paper, a low-power single-phase clock multiband flexible divider for Bluetooth, Zig-bee, and IEEE 802.15.4 and 802.11 a/b/g WLAN frequency synthesizers is proposed based on pulse-swallow topology and is implemented using a 0.18-m CMOS technology. The multiband divider consists of a proposed wideband multi-modulus 32/33/47/48 pre-scalar and an improved bit-cell for swallow (S) counter an...

This paper presents the size miniaturized and harmonic suppressed lossless 1:4 T-junction unequal power divider using an open complementary split ring resonator (OCSRR). By embedding the OCSRR structure in the microstrip transmission line, slow wave effect is introduced and thereby size reduction is achieved. The dimensions of OCSRR are optimized to reduce the length of high impedance and low i...
