DIRECT CONVERSION RECEIVER INCLUDING A CHARGE AREA DECIMATION FILTER |
| 摘要 |
A direct conversion receiver includes: a high linearity mixer device including a sampler unit charge-sampling an input current according to a sampling frequency, and a buffer unit receiving an output signal from the sampler unit while having a low input impedance, amplifying the received signal, and outputting a current signal; and a filter device decimating an output signal from the mixer device and FIR-filtering the decimated signal. |

1. A direct conversion receiver, comprising:
a low noise amplifier amplifying an RF signal input thereto; a transconductance amplifier converting a voltage of the RF signal amplified by the low noise amplifier into a current signal and amplifying the current signal; a mixer device including a sampler unit mixing the current signal amplified by the transconductance amplifier with a local oscillation signal to generate a discrete-time current signal, and a buffer unit amplifying the discrete-time current signal; and a charge area decimation filter decimating the discrete-time current signal output from the mixer device.
