We address the problem of blind carrier frequency-offset (CFO) estimation in quadrature amplitude modulation,
phase-shift keying, and pulse amplitude modulation
communications systems.We study the performance of a standard
CFO estimate, which consists of first raising the received signal to
the Mth power, where M is an integer depending on the type and
size of the symbol constellation, and then applying the nonlinear
least squares (NLLS) estimation approach. At low signal-to noise
ratio (SNR), the NLLS method fails to provide an accurate CFO
estimate because of the presence of outliers. In this letter, we derive
an approximate closed-form expression for the outlier probability.
This enables us to predict the mean-square error (MSE) on CFO
estimation for all SNR values. For a given SNR, the new results
also give insight into the minimum number of samples required in
the CFO estimation procedure, in order to ensure that the MSE
on estimation is not significantly affected by the outliers.

An inductive feedback technique increases the speed
of resonant circuits by 62 , allowing operation near the of
transistors. The technique leads to a fundamental oscillator operating
at 128 GHz with a power dissipation of 9 mW and a phase
noise of 105 dBc/Hz at 10-MHz offset. A divide-by-two circuit
based on the idea and incorporating a sampling mixer achieves a
maximum speed of 125 GHz while consuming 10.5 mW. The prototypes
have been fabricated in 90-nm CMOS technology.(An inductive feedback technique increases the speed of resonant circuits by 62 , allowing operation near the of transistors.
