A 56–65 GHz Injection-Locked Frequency Tripler With Quadrature Outputs in 90-nm CMOS

A sub-harmonic injection-locked tripler multiplies a 20-GHz differential input to 60-GHz quadrature (I/Q) output signals. The tripler consists of a two-stage ring oscillator driven by a single-stage polyphase input filter and 50I and Q-signal output buffers. Each gain stage incorporates a hard limiter to triple the input frequency for injection locking and a negative resistance cell with two po...

CMOS Direct-Injection Divide-by-3 Injection-Locked Frequency Dividers

This paper proposes CMOS LC-tank divide-by-3 injection locked frequency dividers (ILFDs) fabricated in 0.18 μm and 90nm CMOS process and describes the circuit design, operation principle and measurement results of the ILFDs. The ILFDs use two injection series-MOSFETs across the LC resonator and a differential injection signal is applied to the gates of injection MOSFETs. The direct-injection di...

A 90-nm CMOS 144 GHz Injection Locked Frequency Divider with Inductive Feedback

This paper presents a 144 GHz divide-by-2 injection locked frequency divider (ILFD) with inductive feedback developed in a commercial 90-nm Si RFCMOS technology. It was demonstrated that division-by-2 operation is achieved with input power down to -12 dBm, with measured locking range of 0.96 GHz (144.18 – 145.14 GHz) at input power of -3 dBm. To the authors’ best knowledge, this is the highest ...

A 1.6-to-3.2/4.8 GHz Dual-Modulus Injection-Locked Frequency Multiplier in 0.18 m Digital CMOS

This paper proposes a variable-modulus injectionlocked frequency multiplier for better harmonic suppression. It is more suitable for fully-integrated implementation using low-Q on-chip inductors in digital CMOS than conventional approaches. A prototype dual-modulus frequency doubler/tripler with 1.6GHz input and 3.2GHz/4.8GHz output is implemented in a 0.18 m standard digital CMOS. At 5% lockin...

Superharmonic Injection-Locked Frequency Dividers

Injection-locked oscillators (ILO’s) are investigated in a new theoretical approach. A first-order differential equation is derived for the noise dynamics of ILO’s. A single-ended injection-locked frequency divider (SILFD) is designed in a 0.5m CMOS technology operating at 1.8 GHz with more than 190 MHz locking range while consuming 3 mW of power. A differential injection-locked frequency divid...
