A transconductor-tuned 23-to-29 GHz wideband VCO is implemented in 0.13-mum CMOS technology. Tuning is accomplished by exploiting the 90deg phase shift across a transcon- ductor. The frequency is continuously tunable with differential and common-mode

In multiple-input multiple-output (MIMO) communications systems, a crucial role is played by channel estimation as the accuracy of estimation will have a substantial effect on the overall system performance. In this paper we consider designing precod

A 1V 24GHz fully integrated PLL is designed in a 0.18/spl mu/m. CMOS process using a transformer-feedback VCO and a stacked frequency divider. The PLL measures an in-band phase noise of -106.3dBc/Hz at 100kHz offset and an out-of-band phase noise of

Most low dropout regulators (LDRs) have a limited of load current operating range due to stability problems. This paper proposes a new frequency compensation scheme for LDR to optimize the regulator performance over a wide load current range. By intr
